Question
Let \(\vec{F} = \langle P(x, y), Q(x, y) \rangle = \langle xy, x + y \rangle\) and let \(C\) be the circle \(x^2 + y^2 = 4\), oriented counterclockwise (as above). Find the circulation of \(\vec{F}\) around \(C\) by using Green's theorem.

In this case, \(Q_x = \underline{\hspace{1cm}}\) and \(P_y = \underline{\hspace{1cm}}\).

Thus the circulation of \(\vec{F}\) around \(C = \iint_R \underline{\hspace{2cm}} \, dA\), where \(R\) is the region bounded by \(x^2 + y^2 = 4\).

Evaluating this, the circulation of \(\vec{F}\) around \(C\) is \(\underline{\hspace{1cm}}\).
