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.
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
