for those of you who are into polar form, if you have
r = 1-sin(theta) and r=sin(theta)
and you need to find the area of the region BETWEEN inner loops of them, how do you set up the equation?

the formula for area bounded between functions is:
the integral from alpha to beta of 1/2 *[(r2)^2-(r1)^2]d(theta)

alpha and beta would be pi/6 and 5pi/6 in this case, i think

which one is supposed to be used as the farther one(r2) and which one as the closer one(r1) since we have to find the are BETWEEN the two...??

This is just for fun. Don't try to solve it, just explain how you'd set up the problem.

At King John's summer games, the Sheriff of Nottingham, Maid Marian, and Robin Hood are all far apart in a triangle. The sheriff accidentally lofts an arrow that will land on Maid Marian, but a short time later with quick reflexes, Robin carefully takes aim and launches an arrow that deflects the sheriff's projectile, thus saving the Maid's life.

How would you set it up?
