Well I half agree with you...Justin is pretty bad, but lately he is acting like he is black, so I suppose you could compare him to the black eyed peas...

I'm probably too late to be useful, but the answer is:

(x^2 / 4) - (1/8 * cos(2x)) - (1/4 * x * sin(2x))

You've to use the identity integral( sin(x)^2 ) == x/2 - 1/4 * sin(2x)

(whew... haven't integrated anything in a while )

[/QUOTE]Absolutely NOT too late to be useful!...I just could have sworn that we'd never seen that first part before, and whenever I don't think that I'm supposed to know how to do something yet, then I think that I'm going about the problem incorrectly...

Well, thanks, Aleph_null1, I sincerely appreciate it...Calculus II is pwning me so far, but hopefully, with enough studying, I can fix that!

ARGH! This blows. I went to tutoring all day to rush through my chem homework, then went to geography, thinking about a nap. But, no! We had a test, I was completely unprepared for! Bah! Went back to tutoring, got a few more problems done, then went to my chem class. Ended up writing some gobidle-goop down, then the correct answer, a la back of the text book, and hoped. Now, with my classes over for the day, I'm gonna chill a little. Then I get to start studying for my impending chemistry test. Oh, and it's raining and nasty, and the bottom third of my jeans are soaked. Super...

I hadn't noticed that. Entertaining, yes; respectful, no. [img]tongue.gif[/img]
