1. The problem statement, all variables and given/known data
for the vector field E=x(xy)y(x^2 +2y^2) find E.dl along the contour find (nabla)xE along the surface x=0 and x=1 y=0 and y=1 2. Relevant equations 3. The attempt at a solution i tried the second question (nabla)xE over the surface by finding the determinant of the matrix as 2xx=3x so (nabla)xE=3x and integrating along the surface x and y i found the answer to be 3/2 but the answer is meant to be 1 for both cases in order to prove stokes thm

For that vector field and contour, 3/2 is the correct answer.
