1. The problem statement, all variables and given/known data verify greens for the integral (xy^2 i - x^2y j) dot dr over c, where c = y = x^2 from (-1,1) to (1,1). Evaluate both sides independantly to achieve the same answer 2. Relevant equations 3. The attempt at a solution so i took the partials and got -2xy - 2yx = -4xy, shouldnt it equal o.
