Find fracpartial zpartial x and fracpartial zpartial y if x3 + y3 + z3 + 6xyz = 1.
Find $\frac{\partial z}{\partial x}$ and $\frac{\partial z}{\partial y}$ if $x^3 + y^3 + z^3 + 6xyz = 1$. [5]
Implicit relation: $$F(x,y,z) = x^3 + y^3 + z^3 + 6xyz - 1 = 0$$ Required: $\dfrac{\partial z}{\partial x}$ and $\dfrac{\partial z}{\partial y}$, where $z$ is an implicit function of $x$ and $y$. No numeric values are missing; this is a symbolic derivation. --- Finding
