comment Finding suitable basis for a free abelian finitely generated group.
It looks like I am taking the exact same course exactly a year later, as the question fits the one appearing on my homework, no one explained anything about Smith normal form to us, and I have no idea what do to.. (also your name fits the area :P). Let's hope the single answer here will help me get on my way...

comment Finding the function of the power series $\sum\limits _{n=1}^{\infty}\frac{x^{2n+1}}{n}$
That's a lot simpler than my way...

comment Proving differentiability on every interval equals proving differentiability on all of $\mathbb{R}$?
Well, that should have been pretty obvious to me looking back at it.. Thanks for clearing it all up anyway

@JohnMa don't really think I am.. The theorem in Wikipedia doesn't mention anything on a bound for any closed interval. Would it have any affect on all of $\mathbb{R}$ to have such a bound? en.wikipedia.org/wiki/Uniform_convergence#To_differentiability

@Did I didn't really understand your second comment though, but I did take the first one somewhere, and I'd love to know if my answer is correct :P

@Did Thinking about it so far, still not sure.. Definitely feels like I'm missing something simple though..
