I need help with finding areas. I'm having trouble picking the correct limits for my integration.
Say for example we had r=2cos2t and a half-line t=pi/6, and I want to find the small area bounded between them.
[tex]\frac{1}{2}\int (2\cos (2\theta))^{2}\,d\theta[/tex]
I can do the integration, but what do I choose as its limits?
I'm not particularly interested in the answer to this question; I'm looking for a good explanation or maybe a couple of pointers.
