Help with Green Theorem

  1. Feb 22, 2015 #1
    Hello fellows,

    I am not sure if the answer i got this question is the correct one. Could it not be it?

    ∫(y+x^2*cosx)dx+(2x-y^2*sin(y))dy within the llimit of the circle x^2+y^2=1

    Yes, that is correct. Why would you be not sure? It's about as easy a Greens theorem problem as you can have!
