Prove the conjecture made in the previous exercise.
Suppose that a sequence of differentiable functions {fn} converges pointwiseto a function f on an interval [a,b], and the sequence {f′n}converges uniformlyto a function g on [a,b]. Then show that f is differentiable and f′(x) = g(x)on [a,b].
Consider the function f(x)=1/x Show that the interval of convergence is (0, 2).
Suppose we have the sequence of functions $f_n(x)=x^n$ defined on $[0,1],$ and suppose $f_n\to f$ pointwise where $f(x)=0$ if $x\in(0,1]$ and $f(x)=1$ if $x=1.$ Prove that Uniform Convergence fails.
Let (a) Find the pointwise limit of (fn) for all x ∈ (0,∞).(b) Is the convergence uniform on (0,∞)?(c) Is the convergence uniform on (0, 1)?(d) Is the convergence uniform on (1,∞)?
Let (fn) be a sequence of differentiable functions defined on the closed interval [a, b], and assume (fn ) converges uniformly on [a, b]. If thereexists a point x0 ∈ [a, b] where fn(x0) is convergent, then (fn) converges uniformly on [a, b]. Proof. Exercise 6.3.7. Combining the last two results produces a stronger version of Theorem 6.3.1.

(b) The series converges for every x in the half-open interval [−1, 1) but does not convergewhen x = 1. For a fixed x0 ∈ (−1, 1), explain how we can still use theWeierstrass M-Test to prove that f is continuous at x0.

Suppose that fn : [0, 1] → R is defined by fn(x) = x n. If 0 ≤ x < 1, then xn → 0 as n → ∞, while if x = 1, then x n → 1 as n → ∞. So fn → f pointwise where Although each fn is continuous on [0, 1], their pointwise limit f is not (it is discontinuous at 1). Thus, pointwise convergence does not, in general, preserve continuity.
(c) A sequence (fn) of differentiable functions such that both (fn) and (fn )converge uniformly but f = lim fn is not differentiable at some point
