Question:
Use implicit differentiation to find {eq}\displaystyle \frac{\partial z}{\partial x} \ \ and \ \ \frac{\partial z}{\partial y}\ {/eq}.
{eq}x^2 + 4y^2 + 5z^2 = 7 {/eq}
Implicit Partial Differentiation:
Most of the problems we do in differentiation are explicit differentiation. Implicit differentiation, on the other hand, allows us to find {eq}\displaystyle \frac{dy}{dx} {/eq} without solving the equation for y.
In the following problem, we use formulae like:
- {eq}\displaystyle \frac{\partial(x^a)}{\partial x} = ax^{a-1} {/eq}
