F (x, y) = y3/x, p (1, 3), u = 1 3 2i + 5 j (a) find the gradient of f.

Gabriella, it is important that you use "^" to denote exponentiation. "y3" doesn't cut it.

The gradient of F is (partial derivative of F with respect to x) i + (partial with respect to y) j.

Thus, G (x, y) = the gradient in question = (-y^3/x^2) i + (0) j (answer)
