Line integral

    1. The problem statement, all variables and given/known data

    I need to use Green's theorem in order to solve this integral.
    My question is, how can I find the area for the Green's theorem integral?

    2. Relevant equations

    3. The attempt at a solution

    If x= sin t cos t and y= sin2 t, then x2+ y2= sin2tcos2t+ sin4t= sin2 t(cos2 t+ sin2t)= sin2(t)= y so the equation, in Cartesian coordinates, is x2+ y2- y= 0. Complete the square and you can see that is a circle.
