    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?
