Use Green's Theorem to evaluate

F(x, y) = y cos x − xy sin x, xy + x cos x

, C is the triangle from (0, 0) to (0, 4) to (2, 0) to (0, 0)

I kind of understand how to do this , but I am having trouble with the trig

what does the comma mean in

F(x, y) = y cos x − xy sin x, xy + x cos x

?

are we to integrate F around the perimeter of the triangle by integrating the divergence over the area or what ?

Look at earlier questions below.
