# Thread: Area of a Three-Leaved Rose

1. ## Area of a Three-Leaved Rose

I'm supposed to find the area of one loop of a three leaved rose:

r=10cos3ϴ.

I know I'm supposed to integrate the formula (1/2)r^2ϴ, but what do I use as the upper and lower bounds?

what is the first angle, $\theta > 0$ where $\cos(3\theta) = 0$ ? ... what is the next angle after that one?
