I like you usage of icons. I think I'll adopt it. ;) Now, I'm trying to solve an exercise in my math book with this principle. Despite the fact I already learned infinite limits arithmetics, I'm required to prove that lim_\below{x\rightarrow \infty}) x cos\frac{1}{x} = \infty in this cumbersome...

Thanks! :) Let me summarize it to see if I got it. It should be For every N>0 there exists M>0, so that for every x>M, f(x)>N Right?

Homework Statement I am required to express in \varepsilon - \delta way what I'm suppose to prove in case lim_\below{(x \rightarrow \infty)} f(x) = \infty Homework Equations None. The Attempt at a Solution So first, intuitively I thought that what this means is that f(x) is bigger...
