MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER Show that the line integral is independent of path. 2xe Ydx + (2y - x e-V)dy, C is any path from (1, 0) to (5, 1) The functions 2xey and 2y - xe" have continuous first-order derivatives on R2 and - (2xe-V) = ax = ( 2y - x2e -y ), so F (x, y) = ( i + (2y - x2e-V) j is a conservative vector field by the theorem given below, hence the line integral is independent of path. Theorem: Let F = Pi + Qj be a vector field on an open simply-connected region D. Suppose that P and Q have continuous first-order partial derivatives and - ay ax OP = 2 throughout D. Then F is conservative. Evaluate the integral. Need Help? Read It Watch It10. [-/1 Points] DETAILS SCALCET9 16.3.034. Let F = Vf, where f(x, y) = sin(x - 7y).
