\[\int\limits_{0}^{2\pi} \cos^2 (2\theta) d \theta\]

use 1/2 angle formula

So it becomes \[1/2 + 1/2 \cos (4 \theta)\] ??

Um... Something's wrong with what I'm doing. The original question is to find the area of one of the clovers of \[r = \cos2 \theta\] So I did the integration of 0 to 2pi of the equation squared. I then divided by 1/4 to get 1 clover. But I got pi/4 instead of the answer pi/8

remember it is \[\frac12\int_a^b r^2\,d\theta\] did you include the 1/2?
