Solved: 1516 Confirm that is a potential function for F(r) on someregion, and state the
Chapter 15, Problem 16(choose chapter or problem)
Confirm that \(\phi\) is a potential function for F(r) on some region, and state the region.
(a) \(\phi(x, y)=2 y^{2}+3 x^{2} y-x y^{3}\)
F\((x, y)=\left(6 x y-y^{3}\right) i+\left(4 y+3 x^{2}-3 x y^{2}\right) j\)
(b) \(\phi(x, y, z)=x \sin z+y \sin x+\sin y\)
F\(x, y, z)=(\sin z+y \cos x) i+(\sin x+z \cos y) j\)
\(+(\sin y+x \cos z) k\)

phi
phi(x, y) = 2y^2 + 3 x^2y - xy^3
(x, y) = (6xy - y^3) i + (4y + 3 x^2 - 3xy^2) j
phi(x, y, z) = x sin z + y sin x + sin y
(x, y, z) = (sin z + y cos x) i + (sin x + z cos y) j
+(sin y + x cos z) k
