Using Green's Theorem to find the flux












1














$F(x,y)=langle y^2+e^x,x^2+e^yrangle$. Using green's theorem in its circulation and flux forms, determine the flux and circulation of $F$ around the triangle $T$, where $T$ is the triangle with vertices $(0,0),(1,0),$ and $(0,1)$, oriented counterclockwise.



My Try:



$f=y^2+e^x$



$g=x^2+e^y$



$$frac{partial f}{partial y}=2y$$
$$frac{partial g}{partial x}=2x$$
$$int Fcdot dr=intint_R(2x-2y)dA$$
$$int^{1}_{0}int_{0}^{1-x}(2x-2y)dydx=0$$
My quesiton: Is my above attempt correct? Because I got the answer as $0$

          The result is correct indeed we have that the region is symmetric with respect to $y=x$ and the integral for $2x$ is equal to the integral for $2y$ that is



          $$intint_R 2x,dA=intint_R2y,dA implies intint_R(2x-2y)dA=0$$
