SOLUTION: Consider the surface F(x,y,z)=x^6z^2+sin(y^6z^2)−8=0.
Find the following partial derivatives
∂z/∂x=
Mi answer is -((6xz)/(x^6y^6cos(y^6z^2))) but it's wrong.

Question 1180479: Consider the surface F(x,y,z)=x^6z^2+sin(y^6z^2)−8=0.
Find the following partial derivatives
∂z/∂x=
Mi answer is -((6xz)/(x^6y^6cos(y^6z^2))) but it's wrong.
∂z/∂y=
Mi anwer is -((6y^5zcos(y^6z^2))/(2x^6+2y^6cos(y^6z^2))) it's correct.

Today I have the time to add the steps, partly for my own benefit:
F(x,y,z) =
Fx = ∂F/∂x =
Fz =
By the Implicit Function Theorem (see https://www.sfu.ca/~wainwrig/Econ331/notes-partials1.pdf)
∂z/∂x = -Fx/Fz =
Canceling a 2z from top and bottom gives:
