Question
For each of the following vector fields F, decide whether it is conservative or not by computing the appropriate first order partial derivatives. Type in a
potential function f (that is, Vf = F) with f(0,0) = 0. If it is not conservative, type N.
A. F (x, y)
f (x, y) =
(14x + 2y) i+ (2x + 14y) j
=
В. F (х, у) — 7уi + 8aj
f (x, y) =
C. F (x, y)
f (x, y) =
(7 sin y) i+ (4y + 7x cos y) j
Note: Your answers should be either expressions of x and y (e.g. "3xy + 2y"), or the letter "N"
