# Answer to Question #22184 in Integral Calculus for Matthew Lind

Question #22184

Determine whether there is a function phi such that F = grad(phi), where:

a) F = (xz-y)i + (x^2y+z^3)j + (3xz2-xy)k.

b) F = 2xe^(-y)i + (cosz - x^2e^(-y))j - (ysinz)k. If so, find it.

a) F = (xz-y)i + (x^2y+z^3)j + (3xz2-xy)k.

b) F = 2xe^(-y)i + (cosz - x^2e^(-y))j - (ysinz)k. If so, find it.
