Use this definition of a right-hand limit to prove the following limit. EXAMPLE 3 x0 SOLUTION and L such that 1. Guessing a value for 6. Let & be a given positive number. Here a = so we want to find a number 0 x6 if then that is if 0 <x<6 then <E or, raising both sides of the inequality to the eleventh power, we get 0 <x if then x < This suggests we should choose 8= 2....
7. For each of the following, prove that the sequence {a,) converges and find the limit. 2. Qn+1 = (2a, + 5). a, = 2 b. a -1 = V2an, a, = 3 *c. Qn+1 = V2a, + 3. a, - 1 d. 2n+1 = V2a, + 3, a, = 4
Problem 5 A sequence {an) is defined by ay = 1 and an+1 = 3 - Use the Principle of Mathematical Induction (PMI) to show that an is increasing and bounded above by 3 and explam the sequence converges. Using the fact that any converges and an+1 = 3 - find the value of the limit limn+an.

. Prove that sequence in Example 6.2.2 (i) on p.174 converges uniformly to r on any inteval [a, b]. Prove that the convergence cannot be uniform on [0, 0o) J() d tel argue thau Jn J Exercise 6.2.6. Assume fn → f on a set A. Theorem 6.2.6 is an example of a typical type of question which asks whether a trait possessed by each fn is inherited by the limit function.
