Consider the vector field F = (4xy + 1ly - 3, 2x- + 11x). 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) = 4x+11 Preview 4x + 11 syntax ok . If F is conservative, use f(x, y) to evaluate F . di along a piecewise smooth curve (C) from (1,0) to (2,4). F . dr = Preview C
