Question

find first order partial derivatives of the following function Z=3x^3y-xy^2+4y^4​

Answer 1

Step-by-step explanation:

dz/dx=9x^2y-y^2+0

dz/dy=3x^3-2xy+16y^3.

All you need to do is , when differentiate w.r.t x treat y as a constant and vice versa.

hope it helps. let me know, if it's right or not.
