1. The problem statement, all variables and given/known data Use Green's theorem to compute the area of one petal of the 8-leafed rose defined by r=9sin(4theta) It may be useful for recall that the area of a region D enclosed by a curve C can be expressed as A =(1/2)int xdy-ydx. 2. Relevant equations A =(1/2)int xdy-ydx 3. The attempt at a solution I graphed the region on my calculator, but I am not sure what to use for x and y. Would the best way be to change r into rectangular coordinates? If so what would my limit be? 0 to pi/4? perhaps? Thanks in advance!
