In this video we are going to talk about implicit differentiation. In many examples, especially the ones derived from differential equations, the variables involved are not linked to each other in an explicit way. Most of the time, they are linked through an implicit formula, like F(x, y)=0. Once x is fixed, we may find y through numerical computations. The question becomes what is the derivative dy/dx , at least at a certain a point? The method of implicit differentiation answers this concern. The key to these problems is to recognize that y=y(x) and to use the Chain Rule whenever y appears. We will illustrate this through several examples.
