comment Is there a Gronwall-type lower bound inequality?
Oh, I guess so. Thanks!

comment How can I prove that $\sum_{n=1}^\infty \frac{1}{n(n+1)} = 1$?
Your solution bugs me because it reminds me of this: $$ \sum_{n=1}^{\infty}(-1)^n = -1+1-1+1-1+\cdots = (-1+1)+(-1+1)+(-1+1)+\cdots = 0+0+0+\cdots = 0. $$

comment There aren't non-holomorphic polynomials, right?
Yeah, that's what I thought. It reminds me of my first Spanish class in which I learned that I didn't need to say "Yo tengo..." since "Tengo..." was sufficient, and that the "Yo" maybe was just overemphasizing the statement.

comment Sequential compactness in $\mathbb{R}$
Maybe I should have used the notation $f^{-1}\{y_n\}$ to make it more clear that it is a pre-image, rather than an inverse.
