Find fracpartial zpartial x and fracpartial zpartial y if z is defined as a function of x and y by the equation x3+y3+z3+6xyz=1.

Find $\frac{\partial z}{\partial x}$ and $\frac{\partial z}{\partial y}$ if z is defined as a function of x and y by the equation $x^3+y^3+z^3+6xyz=1$. [5]

Equation defining $z$ implicitly as a function of $x$ and $y$: $$x^3 + y^3 + z^3 + 6xyz = 1$$ Required: $\dfrac{\partial z}{\partial x}$ and $\dfrac{\partial z}{\partial y}$. Define $$F(x,y,z) = x^3 + y^3 + z^3 + 6xyz - 1 = 0$$ By the implicit function theorem: $$\frac{\partial z}{\partial x} = -...
