Recall that if S is bounded above, then sup S exists and represents a real number by the completeness axiom 4. Likewise, if S is bounded below, then inf S exists and represents a real number [Corollary 4. For emphasis, we recapitulate: Let S be any nonempty subset of R. The symbols sup S and inf S always make sense. Select some a0 in A. The exercises for this section clear up some loose calculsu.

The remarks in the last paragraph relating real numbers and Dedekind cuts are based on our knowledge of R, including the com- pleteness axiom. But they can also motivate a development of R based solely on Q. In such a development we make no a priori as- sumptions about R. For a naive attempt, see Exercise 6. Introduction Exercises 6.

Does it correspond to a rational number in R? It is customary to de- note a sequence by a letter such as s and to denote its value at n as sn rather than s n. In this chapter, we will be inter- ested in sequences whose range values are real numbers, i. This is the sequence 1, 141916 1 125. Thwory, of course, this is the function with domain N whose value at each n is n It is important to distinguish between a sequence and its set of values, since the validity of many results in this book depends on whether we are working with a sequence or a set.

If we approximate values to four decimal places, the sequence looks like 1, 1. It turns analsyis that a is approximately 1. If we approximate the values to four decimal places, we obtain 2, 2. Also b is approximately 2. For instance, the values of the sequence in Example 1 a are close to 0 for large n and the values of the sequence in Example 1 d appear to be close to 1 for large n. The downloqd s is called the limit of the sequence sn.

A sequence that does not converge to some real number is said to diverge. Several comments are in order. We illustrate these remarks thf the next example. Since we are inter- ested only in integer values of n, we may as well drop the fractional part of N. We could go on and on with these numerical illustrations, but it should be clear we need a more theoretical approach if we are going to prove results about limits.

Example 3 We return to the examples in Example 1. This will be proved in Example 1 of the next section. We will discuss this example again in Example 4 of prf next section. See Downnload 8.

Recall e is approximately 2. We conclude this section by showing analsis limits are unique. Exercises 7. If it converges, give its limit. No proofs are required. No proofs are required, but show any relevant algebra. With a little study and practice, students should be able to do proofs of this sort themselves. We will some- times refer to a proof as a formal proof to emphasize it is a rigorous mathematical proof.

As is often the case with trigonometric identities, we will initially work backward from our desired conclusion, but in the formal proof we calculua have to be sure our steps are reversible. Sequences Discussion. So we will simplify matters by making estimates. Example 3 illustrates direct proofs of even rather simple limits can get complicated. Sequences Now by the Triangle Inequality 3. But we can hope to show such N exists. So we consider two cases. This case is left to Exercise 8.

This seems clear from Fig. Formal proofs are required in the following exercises. Exercises 8. This will complete the proof for Example 5. Limit Theorems for Sequences 45 8. First we prove convergent sequences are bounded. Convergent sequences are bounded. In the proof of Theorem 9. Sequences 9. If the sequence sn converges to s analysis k is in R, then analyxis sequence ksn converges to ks.

If sn converges to s and tn converges to t, then sn tn converges to st. Limit Theorems for Sequences 47 Discussion. Fortunately, Theorem 9. By Theorem 9. Sequences and it is ana,ysis how our proof should proceed. Suppose sn converges to s and tn converges to t. Proof By Lemma 9. The preceding limit theorems and a few standard examples allow one **calculus** easily calculate many limits. Limit Theorems for Sequences 49 analysiss binomial theorem [Exercise 1. Lemma 9.

Hence by Theorems 9. We give some examples. The limit in Wlementary 6 would be easier to handle if we could apply a limit theorem. But the limit Theorems 9. Do not attempt to apply the limit Theorems 9. Use Theorem eoementary. Limit Theorems for Sequences 53 see Exercise 8. So by Theorem 9. Here is another useful theorem. Proof Let **the** be a sequence of positive real numbers. This proves 1. To prove 2we abandon the notation of the last paragraph and begin anew.

Exercises 9. Justify all steps. Exercises 55 9. Use Exercise 9. Sequences an 9. These theorems are cqlculus because in practice the limits are not usually known in advance. A sequence that is increasing ele,entary decreasing4 will be called a monotone sequence or a monotonic sequence. Monotone Sequences and Cauchy Sequences 57 1 sequence cn. Of the sequences above, ancndnsntnvn and xn elementarg bounded sequences.

The remaining sequences, bn and unare unbounded sequences. All bounded monotone sequences converge. Proof Let sn be a bounded increasing sequence. Since S is bounded, u represents a real number. The proof for bounded decreasing sequences is left to Exercise Note the Completeness Axiom 4. We will show limn sn exists by showing the sequence is decreasing and bounded; see Theorem Hence 2 holds for all n by induction.

To calcuulus this, we apply the limit Theorems 9. We have not given much attention to the notion that real numbers are simply decimal expansions. This notion is **theory** correct, but there are subtleties to be faced. We restrict our attention to nonnegative decimal expansions and nonnegative real numbers. From our point of view, every nonnegative decimal expansion is shorthand for the limit of a bounded increasing sequence of real numbers.

Suppose we **download** given a decimal expansion K. So by Theorem Monotone Sequences and Cauchy Sequences 59 a real number we traditionally write as K. For example, 3. Similarly, 0. The teh of the preceding discussion also holds. That is, every nonnegative real number x has at least one decimal expansion. Unbounded monotone sequences also have limits. Proof i Let sn tbe an **pdf** increasing sequence.

Sequences Calculu lim sn is always meaningful for monotone sequences. Proof Apply Theorems Let sn be a bounded sequence in R; it may or may not converge. By Theorem The numbers u and v are useful whether lim sn exists or not and are denoted lim inf sn and lim sup snrespectively. Let sn be a sequence in R. However, we adopt the following conventions.

Similar remarks apply to lim inf sn. Let M be a positive real analysia. We leave these two special cases to the reader. This leads us to a concept of great theoretical importance that will be used throughout the book. Monotone Sequences and Cauchy Sequences 63 Convergent sequences are Cauchy sequences. Cauchy sequences are bounded. Proof The proof is similar to that of Theorem 9. A sequence is a convergent sequence if and only if it is a Cauchy sequence.

To check iiconsider a Cauchy sequence sn and downloav sn is bounded by Lemma The opposite inequality always holds, so we have established tne. The proof of Theorem Exercises Prove sn is a Cauchy sequence and hence a convergent sequence. See also Exercise Sequences 1 Here are some alternative ways to approach this concept.

Subsequences 67 also. The positive terms of this sequence comprise a subsequence. The proof is a little bit complicated, but we will apply the theorem several times rather than having to recreate a similar proof several times. Let sn be **download** sequence. In each case, the subsequence can be taken elementar be monotonic. We focus on the other implications. Such subsequences of sn are boring monotonic sequences converging to t. We assume 1 holds, and leave the case that 2 holds to the reader.

Suppose n1n2. This completes the proof of iand is the crux the the full proof. This is possible, since sn is unbounded above. Sequences Example 3 It can tehory shown that the set Q of rational numbers can be listed as a sequence rnthough it is tedious to specify an exact formula. Figure The sequence sn need not converge or even be bounded, but it has a subsequence converging monotonically to 0.

The next theorem is almost obvious. Subsequences 71 If the sequence sn converges, then every subsequence converges to the same limit. Proof Let snk denote a subsequence of sn. First we prove a theorem about monotonic subsequences. Every sequence sn has a monotonic subsequence. Hteory 2. Se- lect n1 so that sn1 is beyond all the dominant terms of the sequence. The elegant proof te Theorem pxf Bloom and is based on a solution in D. Every bounded sequence has a **pdf** subsequence.

Proof If sn is a bounded sequence, it has a **analysis** subsequence by **Download** The Bolzano-Weierstrass theorem is very important and will be used at critical points in Chap. Our proof, based on Theorem Many of the notions introduced in this chapter **pdf** equally good sense in more general settings. For example, the ideas of convergent sequence, Cauchy sequence and bounded sequence all make sense for a se- quence sn where each sn belongs to the plane.

But the idea of a monotonic sequence does not carry over. It turns out that the Bolzano-Weierstrass theorem also holds in the plane and in many other settings [see Theorem Since the Bolzano-Weierstrass Theorem We need one more notion, and then we will be able to tie our various concepts together in Theorem The interesting case is when the original sequence does not have a limit.

Example 7 Let rn be a list of all rational numbers. It was shown in Example 3 that every real number is a subsequential limit of rn. Let pvf be any sequence. There exists a monotonic subsequence whose limit is lim sup snand czlculus exists a monotonic **theory** whose limit is lim inf sn. Sequences Proof If sn is not bounded above, **elementary** by Theorem The remaining cases are that sn tehory bounded above or is bounded below.

Let sn be **calculus** sequence in R, and let S tye the set of subsequential limits theory sn. Proof i **calculus** an immediate consequence of Theorem elementaryy To prove iiconsider any limit t of a subsequence snk of sn. Subsequences 75 Theorem Therefore off holds. Assertion iii caoculus simply a reformulation of Theorem Theorems We return to the examples given before Theorem The next result shows that the set **The** of subsequential lim- its always contains all limits of sequences from S.

Such sets are called odf sets. Let S denote the set of **analysis** limits of a sequence sn. Then t belongs to S. Then some tn is in this interval. Thus, by Theorem Compare Exercise Most of the material is given in the exercises. We illustrate the techniques **elementary** proving some results that will be needed later in the text. Case 1. Case 3. Hence 1 is obvious in this case.

We diwnload now established 1 in all cases. For the reversed in- equality, we resort to a little trick. This inequality and 1 prove the theorem. Example 1 The hypothesis s be positive in Theorem Let sn be any sequence of nonzero real numbers.

Sequences Proof The middle inequality is obvious. Consequently 1 holds as desired. This follows **elementary** part a and Exercise Sequences Exercises Then apply Exercise 9. Hint : Use Exercise Most of our analy- sis could have been based on the notion of distance, in which case it becomes easy and natural to work in a more general setting. Such a function d is called a distance function or a metric on S. A metric space S is a set S together with a metric on it.

Properly speaking, the metric space is the pair S, d since a set S may well have more than one metric on it; see Exercise Then dist is a metric on R. Note Corollary 3. In fact, for any metric d, property D3 is called the triangle inequality. As noted in Exercise The triangle inequality D3 is not so obvious. The metric space S, d is said to be complete if every Cauchy sequence in S converges to some element in S. Since the Completeness Axiom 4. Theorem We could just as well have taken as an axiom the completeness of R, dist as a metric space and proved the least upper bound property in 4.

We did not do theory because the concept of least upper bound in R seems to us more fundamental than the concept of Cauchy sequence. We will prove Rk is complete. But we have a notational problem, since we like subscripts for sequences and for coordinates of points in **Pdf.** A sequence x n n in Rk is a Cauchy sequence if and only if each sequence xj is a Cauchy sequence **download** R. Euclidean k-space Rk is complete.

Proof n Consider a Cauchy sequence x n in Rk. By Lemma Hence by Theorem We now prove the Bolzano-Weierstrass theorem for Rk ; compare Theorem Every bounded sequence in Rk has a convergent subsequence. Proof n Let x n be a bounded sequence in Rk. Then each sequence xj is bounded in R. By the same theorem, we may replace x n by a subsequence of the subsequence such that n n x2 converges. Of course, x1 still converges by Theorem This sequence represents a subsequence of the **analysis** sequence, and it converges in Rk by Lemma Let S, d be a metric space.

Let E be a subset of S. The set E is open in S if every point in E is interior to E, i. One can show [Exercise Our study of **Download** and the exercises suggest that metric spaces are fairly general and useful objects. When one is interested in conver- gence of certain objects [such as points or functions], there is often a metric that assists in the study of the convergence. But sometimes no metric will work and yet there is still some sort of convergence analysis tion.

Frequently the appropriate vehicle is what is called a topology. This is a set S for which certain subsets are decreed to be open sets. We will not pursue this abstract theory. Because calculus iii in Discussion To get a feel for these notions, we state some easy facts and leave the proofs as exercises. Let E be a subset of a metric space S, d. Example 3 In R, open intervals a, b are open sets. Closed intervals [a, b] are closed sets. The interior of [a, b] is a, b. Every open set in R is the union of a disjoint sequence of open intervals [Exercise A closed set in R need not be the union of a disjoint sequence of closed intervals and points; such a set appears in Example 5.

This is proved in Theorem Many sets are neither open nor closed. Let Fn be a decreasing sequence [i. Proof Clearly F is closed and bounded. It is the nonemptiness that needs proving! For each n, select an element xn in Fn. By the Bolzano-Weierstrass Theorem Thus **analysis** belongs to Fn0 by b of Proposition Example 5 Here is a famous nonempty closed set in R called the Cantor **pdf.** The Cantor set has some remarkable properties.

For more details, see [62, 2. A family U of open sets is said to be an open cover for a set E if each point of E belongs to at least one set in U, i. In Rkcompact sets are nicely characterized, as follows. A subset E of Rk is compact if and only if it is closed and bounded. Proof Suppose E is compact. It follows that E is bounded. Hence E is a closed set. Now suppose E is closed and bounded. We do so in the next proposition after some preparation. The set F in the last proof is a k-cell because it has the following form.

There exist closed intervals [a1b1 ], [a2b2 ]. Thus a 2-cell in R2 is a closed rectangle. Every k-cell F in Rk is compact. Proof Assume F is not compact. This point belongs to some set U0 in U. Example 6 Let E be a nonempty subset of a metric space S, **calculus.** Hence 1 holds. Show that E is compact if and only if every sequence in E has a subsequence converging to a point in E.

Show sup E and inf E belong to E. Show that distinct x n cannot belong to the same member of U. We now do so. Absolutely convergent series are convergent, as we shall see in Corollary These are the easiest series to sum. Example 2 Formula 2 of Example 1 and the next result are very important and both should be used whenever possible, even though we will **analysis** prove 1 below until the next section.

Series 97 number p. Here are **elementary** remarkable formulas that can be shown by techniques [Fourier series or complex variables, to name two possibilities] that will not be covered in this text. It is worth emphasizing that it is often easier to prove limits exist or series converge than to determine their exact values. In particu- lar, 3 in We next give several tests to assist us in determining whether a series converges.

Absolutely convergent series are convergent. We next state the Ratio Test which is popular because it is often easy to use. Moreover, an important result concerning the radius of convergence of a power series uses the Root Test. We give the proof after the proof of the Root Test. Then clearly an converges; see Exercise Inequality 1 in the proof of the Ratio Test shows that the Root Test is superior to the Ratio Test in the following sense: Whenever the Root Test gives no information [i.

Series which converges by the Root Test. Nevertheless, the tests usually fail together as the next remark shows. We **analysis** three tests for convergence of a series [Comparison, Ra- tio, Root], and we will obtain two more in the next section. Of course, none of these tests will give us the exact value of the series 1. As noted in Before trying the Comparison Test we need to decide whether we believe the series converges or not.

Since n2 converges, the series 1 converges by the Comparison Test. Hence the series 1 converges by the Ratio Test. It is also possible to show 1 converges by comparing it with a suitable geometric series. Therefore the series 1 diverges by Corollary Since the terms of the series 1 are not all nonnegative, we will not be able to use the Comparison Test It turns out that this series converges by the Alternating Series Test Justify your answers.

Hint : Use Theorem Then the series both converge or else they both diverge. Prove this. Hint : This is almost **elementary** from Theorem Compare Example 8. Show an is a geometric series. Prove there is Here are some sums that can be handled. We illustrate. The series diverges very slowly.

However, an integral test is useful to establish the next result. Actually, we have already mentioned 2 [without proof! The techniques just illustrated can be used to prove the following theorem. Since n diverges, 1 we **calculus** that np diverges by the Comparison Test. The interested reader may formulate and prove the general result [Exercise Proof We need to show that the sequence sn converges. See Exercise There we considered a decimal expansion K. We will prove the converse after we formalize the process of long division.

The development here is based on theory suggestions by Karl Stromberg. Fig- ure If we name the digits d1d2d3. Now Eq. Thus by induction, 5 holds for all n. Every nonnegative real number x has at least one decimal expansion. The proof will be similar to that for results in As noted in Discussion Similarly, 2. The next theorem shows this is essentially the only way a number can have distinct decimal expansions.

If x has decimal **elementary** K. The reader can easily check these claims [Exercise Now suppose x has two distinct decimal expansions K. Sequences a contradiction. An expression of the form K. We call such an expansion a repeating decimal. Example 1 Every integer is a repeating decimal. We evaluate this as follows: 3. By the usual long division process in If the details seem too complicated to you, move on to Examples 4—7. A real number x is rational if and only if its decimal expansion is repeating.

As we saw in Since a and b are integers, each rk is an integer. Example 4 An expansion such as. These facts and many others are proved in a fascinating book by Ivan Niven [49]. Sequences must be a positive integer. Claim 1. First, we obtain a recursive relation for In ; see 3. We use integration by parts Theorem Claim 2.

Sequences As noted in Exercise 9. So, for large n, the integer bn In lies in the interval 0, 1a contradiction. Zhou and Markov use a similar technique to prove tan r is irrational for nonzero ratio- nal r and cos r is irrational if r 2 is a nonzero rational. Example 7 There is a famous download introduced by Euler over years ago that arises in the study of the gamma function. The remark in Ex- ercise Exercises 11 **elementary** Note the interesting pattern.

Each sn has a decimal n n n n expansion 0. Remark : This shows the elements of 0, 1 cannot be listed as a sequence. Most of the calculus involves the study of continuous functions. In this chapter we study continuous and uniformly continuous functions. Properly speaking, the symbol f represents the function while f x represents the value of the function at x. However, a func- tion is often given by specifying its values and without mentioning its domain.

Continuity real-valued function. Let f be a real-valued function whose domain is a subset of R. The function f is said to be continuous if it is continuous on dom f. The next theorem says this in another way. Now assume f is continuous at x0but 1 fails. This shows f cannot be continuous at x0contrary to our assumption.

Hence f is continuous at each x0 in R. The graph of f in Fig. Prove f is continuous at 0. The function f in Example 2 is also continuous at the other points of R; see Example 4. Show f is discontinuous, i. Let f be a real-valued function. Here is an easy theorem. Continuity Proof Consider a sequence xn in dom f converging to x0. Theorem 9. This proves kf is continuous at x0. These new functions are continuous if f and g are continuous. Let f and g be real-valued functions that are continuous at x0 in R.

Likewise, Theorem 9. Then Theorem 9. Example 4 For this example, let us accept as known that polynomial functions and the functions sin x, cos x and ex are continuous on R. Then 4ex and sin x are continuous on R by Theorem The function x4 sin x is continuous on R by ii of Theorem Several applications of Theorems Example 5 Let f and g be continuous at x0 in R. Prove max f, g the continuous at x0. However, we illustrate a useful technique by reducing the problem to results we have already established.

By The- orem Be sure to specify their domains. Use these facts and theorems in this section to prove the following functions are also continuous. Prove every rational function is continuous. Hint : Use part a. Show f is discontinuous at every x in R. Properties of Continuous Functions Show P is discontinuous at every positive integer. Because postage rates tend to increase over time, A and B are actually functions. Let f be a continuous real-valued function on a closed interval [a, b].

Then f is a bounded function. Download Assume f is not bounded on [a, b]. By the Bolzano- Weierstrass Theorem The number x0 also must be- long to the closed interval [a, b], as noted in Exercise 8. It follows that f is bounded. By the Bolzano-Weierstrass theorem, there is a subsequence ynk of yn converging to a limit y0 in [a, b]. Thus f **the** its maximum at y0. It follows easily that f assumes its minimum at x0 ; see Exercise If the domain is not a closed interval, one needs to be careful; see Exercise Example 1 Let f be a continuous function mapping [0, 1] into [0, 1].

A rigorous proof involves a little trick. Properties of Continuous Functions Therefore f is one-to-one and each nonnegative y has exactly one nonnegative mth root. Let f be a continuous strictly increasing function on some interval I. Then f I is an interval J by Corollary Let g be a strictly increasing function on an interval J such that g J is an interval I. Then g is continuous on J. Proof Consider x0 in J. We assume x0 is not **calculus** endpoint of J ; tiny changes in the proof are needed otherwise.

However, Exercise Let f be a one-to-one continuous function on an interval I. By the Intermediate Value Theorem This contradicts the one-to-one property of f. We will show f is strictly increasing on I. Where does it break down? Uniform Continuity Show there exists an unbounded continuous function on S. The- orem Such functions are said to be uniformly continuous on S.

We will say f is uniformly continuous if f is uniformly continuous on dom f. It makes no sense to speak of a function being uniformly continuous at each point. It is now straightforward to verify 1. The squeamish reader may skip this demonstration and wait for the easy proof in Example 6. Uniform Continuity We were lucky! How- ever, these results are not accidents as the next important theorem shows.

If f is continuous on a closed interval [a, b], then f is uniformly continuous on [a, b]. Proof Assume f is not uniformly continuous on [a, b]. We conclude f is uniformly continuous on [a, b]. Continuity The preceding proof used only two properties of [a, b]: a Boundedness, so the Bolzano-Weierstrass theorem applies; b A convergent sequence in [a, b] converges to an element in [a, b].

As noted prior to Theorem Hence Theorem If f is continuous on a closed and bounded set S, then f is uniformly continuous on S. See also Theorems Example 5 In view of Theorem Example 5 illustrates the power of Theorem One of the important applications of uniform continuity concerns the integrabil- ity of continuous functions on closed intervals. To see the relevance of uniform continuity, consider a continuous nonnegative real-valued function f on [0, 1]. Then the sum of the areas of the rectangles in Fig.

Relation 1 may appear obvious from Fig. The next **theory** theorems show uniformly continuous functions have nice properties. If f is uniformly continuous on a set S and sn is a Cauchy sequence in S, then f sn is a Cauchy sequence. This proves f sn is also a Cauchy sequence. Then sn is obviously a Cauchy sequence in 0, 1.

Therefore f cannot be uniformly continuous on 0, 1 by Theorem The next theorem involves extensions of functions. The function g **pdf** Example 8 does not extend to a continuous func- tion on the closed interval, and **calculus** turns out that g is not uniformly continuous.

These examples illustrate the next **pdf.** Suppose now that f is uniformly continuous on a, b. To prove 1note that sn is a Cauchy sequence, so f sn is also a Cauchy sequence by Theorem Hence f sn converges by Theorem To prove 2 we create a third sequence un such that sn and tn are both subsequences of **the.** Here is another **download** criterion that implies uniform continuity.

Proof For this proof we need the Mean Value theorem, which can be found in most calculus texts or later in this book [Theorem This proves the uniform continuity of f on I. For a direct proof of this fact, see **Pdf** 2. Use any theorems you wish. Hint : Assume not. Use Theorems Justify your answers, using appropriate theorems or Exercise Compare with Theorem Limits of Functions In this section we formalize this notion.

This section is needed for our careful study of derivatives in Chap. Continuity b Observe that limits, when they exist, are unique. Exercise 9. This establishes 1. It theory [Exercise 9. Of course, a direct proof of 2 also can be given. First we prove some limit theorems in considerable generality. Consider a sequence xn in S with limit a. Theorems 9. **The** iii follows by an application of Theorem 9. The next theorem is less general than might have been expected; Example 7 shows why.

This follows immediately from Theorem Example 7 We give an example to show continuity of g is needed in Theo- rem Limits of Functions As in Theorem First we state and prove a typi- cal result of this **theory.** The reason is the electronic devices divert your attention and also cause strains while reading eBooks.
