comment Uniform convergence and maximum of an absolute difference
Let $\epsilon = 1$, $f_n = x^n$ and let our interval be $(0,1)$. $|f_n(x) - f(x)|<1$ but $\sup_{x \in S} |f_n(x) - f(x)| = 1$ for all $n$.

comment Proving partial sums $A_n = o(|z_k|^\rho)$, where $|z_k|\to\infty$ is increasing
Wait a minute, I see it now! OK, so we define $n_0$ by splitting $\sum a_n$, for some reason, I missed that the first time around.

Let us continue this discussion in chat.

How are we justified in applying the triangle inequality? If you mean that $A_k$ converges, and you're applying a convergence argument, how do we know that $n_0$ is large enough?

How do we conclude that $|A_k - A_{n_0}| < \epsilon$ when we chose $n_0$ according to the sequence $b_n$ and not $a_n$?

I do want this result, but I want to know how to prove it.
