real analysis 1,3,8,11,12 please 4.4.3 4.4.11a Limits and Continuity 4 Chapter Remark: In the statement of Theorem 4.4.12 we assumed that f was tone and continuous on the interval I. The fact that f is either stric tric. strictly decreasing on / implies that f is one-to-one on t one-to-one and continuous on an interval 1, then as a consequence of the value theorem the function f is strictly monotone on I (Exercise 15). This false if either f is...
Analysis: Give two examples where if fn does not converge to f uniformly on E, but does converge to f pointwise on E, then the following two theorems do not hold. Write clearly and explain and proof your claims. 711 Theorem Suppose fn→f uniformly on a set E in a metric space. Let x be a limit point of E, and suppose that (15) Then (A,) converges, and (16) lim f()im A In other words, the conclusion is that lim...
