comment Convergence of a power series function
GEdgar, how do you argue $r_n T^n \to 0$ from $\sum r_n x^n$? $r$ is convergent so $|r_n| T^n \le A\ \forall n.$ but why should it go to zero?

comment Convergence of a power series function
GEdgar, If the sequence $|w_n|T_n$ is bounded, the series doesn't converge at $x_0$ necessarily, right? Because I guess this is what you are saying in the second paragraph

comment Integral of derivative
Martin: How do you know that $f(x)$ is integrable on $[a+1/n, b+1/n]$?

comment absolute continuity in trigonometric functions
I have! But I don't understand it! At $c_k \in (\frac{1}{(k+1)\pi},\frac{1}{k\pi})$ none of $f, f', f''$ are zero! take $\frac{1}{1.5\pi}$ for example
