1. The problem statement, all variables and given/known data Find the area between the curves: x = r(theta-sin(theta)), y = r(1-cos(theta)) 2. The attempt at a solution Usually I would just change the parametric equations into a single equation by solving for theta and substituting back into one of the equations. But that results in a nasty expression that I can't integrate. Basically neither my text nor my professor ever explained how to find the area between two parametric curves and I don't know how to approach the problem. Should I subtract the integrals with respect to theta, using the end points for theta where x=y?
