Posted by jane on Friday, February 27, 2009 at 1:22am.

f(x) = cos(x) - (cos(x))^2 for -pi is less than or equal to x is less than or equal to pi

1) x-intercepts?
2) x and y coordinates of all relative maximum points?
3) intervals on which f is increasing?

then i have to sketch f, so tips on doing so would be appreciated. thank you!
