Homework Statement
Use Green's Theorem to evaluate ∫F*dr.
(Check the orientation of the curve before you applying the theorem.)
F(x,y)=<y2cos(x), x2+2ysin(x)>
C is the triangle from (0,0) to (2,6) to (2,0) to (0,0)
*=dot product

Green's Theorem
The Attempt at a Solution
-∫∫2x+2ycos(x)-2ycos(x) dydx= -∫∫[tex]_{D}[/tex] 2x dydx
D={0[tex]\leq[/tex]y[tex]\leq[/tex]3x, and 0[tex]\leq[/tex]x[tex]\leq[/tex]2)
I put the negative out front because the problem goes from point to point in a clockwise direction. Is this set up correct?
Thank you for your time.
