1. Find the derivative of the function f(x) = 2xy – 3 y’at P,(5,5)

1.	1. Find the derivative of the function f(x) = 2xy – 3 y’at P,(5,5) in the given direction ofu=4i +3j.
Answer» Answer: To find the GRADIENT, TAKE the derivative of the function with respect to X , then substitute the x-coordinate of the point of interest in for the x VALUES in the derivative. So the gradient of the function at the point (1,9) is 8 .
