How to use Green's Theorem to find area bounded by two curves?

41 Views Asked by At

Just starting out for calculus but are you able to help explain how to use Green's Theorem. How to fins the area bounded by the curves:

$x = a\cos^3{t}, y = a\sin^3{t}, (0 \leq t \leq 2\pi)$

How do I use the theorem for this context?

You can take in Green's formula $P=0, Q=x$ or/and $P=-y, Q=0$ and obtain $$S=\int_\limits{\partial G^+}xdy=-\int_\limits{\partial G^+}ydx=\frac{1}{2}\int_\limits{\partial G^+}(xdy-ydx)$$ Can you finish from here?
