I wrote this about a month and a half ago while working on this review, and thought I should share it here. This is a classic problem given to beginner calculus students. I chose this one because it's fairly short, pretty interesting if you've never encountered it before, and because it allowed me to demonstrate a lot of the capabilities of LyX. I thought I should post it here.
