## How do I perform implicit differentiation?

In implicit differentiation, we differentiate each side of an equation with two variables (usually and ) by treating one of the variables as a function of the other. This calls for using the chain rule.

Let's differentiate for example. Here, we treat as an implicit function of .

Notice that the derivative of is and not simply . This is because we treat as a function of .
