For one reason, many of these ideas will be already familiar to the students — at least informally. If the students have already studied abstract algebra, number theory or combinatorics, they should be familiar with the use of mathematical induction.

If not, then some time should be spent on mathematical induction. However, we believe that it is not necessary to go into the proofs of these results at this time. Section 1. This type of element-wise argument is very common in real analysis, since manipulations with set identities is often not suitable when the sets are complicated. Sample Assignment: Exercises 1, 3, 9, 14, 15, Partial Solutions: 1.

This shows. The opposite inclusion is shown in Example 1. The proof for unions is similar. Show that this function works. Many examples are possible. See Example 1. Thus f is injective. Thus g is surjective. Since may students have only a hazy idea of what is involved, it may be a good idea to spend some time explaining and illustrating what constitutes a proof by induction.

The truth of falsity of the individual assertion is not an issue here. Sample Assignment: Exercises 1, 2, 6, 11, 13, 14, Probably every instructor will want to show that Q is countable and R is uncountable see Section 2. The teacher must avoid getting bogged down in a protracted discussion of cardinal numbers. Sample Assignment: Exercises 1, 5, 7, 9, If b also maps into 1, then c must map into 2; if b maps into 2, then c can map into either 1 or 2.

Thus there are 3 surjections that map a into 1, and there are 3 other surjections that map a into 2. The bijection of Example 1. There are also 2n subsets of type ii. See Exercise Therefore Theorem 1. A few selected theorems should be proved in detail, since some experience in writing formal proofs is important to students at this stage. However, one should not spend too much time on this material. Sections 2. These sections should be covered thoroughly. Also the Nested Intervals Property in Section 2.

Section 2. Sample Assignment: Exercises 1 a,b , 2 a,b , 3 a,b , 6, 13, 16 a,b , 20, Now apply 2. Therefore, Theorem 2.

Use Theorem 2. Many other examples are possible. Then by Example 2. This contradicts a. We have put it in a separate section to give it emphasis. Many students need extra work to become comfortable with manipulations involving absolute values, especially when inequalities are involved.

Sample Assignment: Exercises 1, 4, 5, 6 a,b , 8 a,b , 9, 12 a,b , Partial Solutions:. The graph consists of a portion of a line segment in each quadrant. The other cases are similar.

This property is vital to real analysis and students should attain a working understanding of it. Sample Assignment: Exercises 1, 2, 5, 6, 9, 10, 12, Any negative number or 0 is a lower bound. S2 has lower bounds, so that inf S2 exists. S2 does not have upper bounds, so that sup S2 does not exists. See Exercise 7 below. Note that both are members of S4. It is interesting to compare algebraic and geometric approaches to these problems. If z is. Consider two cases.

The Archimedean Properties 2. The exercises also contain some results that will be used later. Sample Assignment: Exercises 1, 2, 4 b , 5, 7, 10, 12, 13, Apply the Archimedean Property 2. It is an interesting fact that if we assume the validity of both the Archimedean Property 2. Hence these two properties could be taken as the completeness axiom for R. There are other properties that could be taken as the completeness axiom.

The discussion of binary and decimal representations is included to give the student a concrete illustration of the rather abstract ideas developed to this point. However, this material is not vital for what follows and can be omitted or treated lightly. We have kept this discussion informal to avoid getting buried in technical details that are not central to the course. Sample Assignment: Exercises 3, 4, 5, 6, 7, 8, 10, S has an upper bound b and a lower bound a if and only if S is contained in the interval [a, b].

Because z is neither a lower bound or an upper bound of S. See More. This shows Chapter 1 — Preliminaries Chapter 1 — Preliminaries Chapter 2 — The Real Numbers 9 Chapter 2 — The Real Numbers 11 8. If z is Chapter 2 — The Real Numbers This sample only, Download all chapters at: alibabadownload. Published on Apr 4, Go explore.
