The realization that you are significantly older than most of us coupled with your use of the word "n00b" is kind of funny, Attalus...though I don't mean to offend...
I think, though, that if my father said "n00b" out loud (and I'm pretty sure he's older than you, so please don't think I'm calling you old) I would snort whatever I was drinking...
Anyway, so I can't figure out the integral of x sin^2 (x) dx...
...I've spent two hours thinking about it, and I'm no closer, as integration by substitution seems to get me nowhere, and I'm under the impression that I'm NOT supposed to just look up the integral of sin^2 (x)...especially when I don't know how to arrive at that conclusion...
Pre-algrebra is mostly filled with learning how to manipulate very simple functions, and doing LOTS of arithmatic...
