comment Simple calculus question (limits)
what about getting rid of all those fractions? Simplify both the numerator and denominator, then apply hopital or better taylor expansions :-)

@bws ops no I'm sorry, you are correct. Yours is the correct solution :-)

comment Integral on the real line between 0 and infinity using contour integration
@bws actually is $\pi/\sqrt 2$ :-)

comment double integral $\int_0^t \int_0^s \frac{\min(u,v)}{uv} \, dv \, du$
divide the region over which you are integrating in two parts, one who has $u > v$ and the other with $v > u$. Calculate those integrals separetely and sum :-)

comment “Averaging” transformation matrices?
I'm afraid you're going have to be a bit more specific.. Start with your background or why does that interest you (concisely). The term transformation matrix, for example, is weird (to me); aren't they just matrices?

comment What is an adjective for “weaker than weak”?
or if you want to go for the win you could also call it "Chen convergence" :-P

comment What is an adjective for “weaker than weak”?
are you sure you need to use the term weak? be a bit more creative! for example in probability one gets convergence almost surely => in probability => in law (also known as weak). You can take inspiration as how and why this new type of convergence was defined in the first place. Say you need it to show that a certain property, called "friendly" holds. Call this new type of convergence friendly convergence, or something like that! just an idea :)

comment Show, directly from the definition, that the following series is convergent.
hi and welcome to math.SE! You can see that your answer is begin downvoted and will probably be closed because, as it is, it's not in scope on this site. You should include what you have tried, what you have problems with, etc. In general we are here to help you learn, not to do your homework for you :)

comment How to show convergence of $\sum_{n=1}^{\infty}\log(1 + \frac{1}n)$?
@LeBtz Yes! or $\lim \frac{a_n}{b_n} = c \neq 0$ :)

comment Contour integral $|z-i|=1/9$
@bws Yes. I added a little explanation but the basic point is that. :)
