Consider the vector field F = (10ry + 10y - 5, 5x* + 10x). O The vector field is not conservative O The vector field is conservative, and the potential function such that f(0, 0) = 0 for F is f(I, y) = Preview If F is conservative, use f(x, y) to evaluate F . dr along a piecewise smooth curve (C) from (1,3) to c (-4,4). F . di = Preview
