As in most cases that require implicit differentiation, the result in in terms of both x and y. In general, if giving the result in terms of x alone were possible, the original expresson could be solved for y as an explicit function of x, and implicit differentiation, while still correct, would not be necessary.

The question becomes what is the derivative , at least at a certain a point? The method of implicit differentiation answers this concern. Let us illustrate this through the following example.

Implicit function - Wikipedia, the free encyclopedia
In mathematics, an implicit function is a function in which the dependent variable has not been given "explicitly" in terms of the independent variable. To give a function f explicitly is to pr...

This process is known as implicit differentiation. ... However, we can no longer expect the derivative to depend only on , but rather on the point on the circle in which we are interested. Implicit differentiation is a process which will clarify this for us.
