IFor 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.
А. F (х, у) — (6х + у)і + (х + 4у)j
f (x, y) =
В. F (х, у) — Зуi + 4xj
f (x, y) =
C. F (x, y) = (3 sin y) i+ (2y + 3x cos y)j
f (х, у) —
Note: Your answers should be either expressions of x and y (e.g. "3xy + 2y"), or the letter "N"
