How to Use implicit differentiation to find a 2nd derivative

An educational video by http://JustMathTutoring.com that shows how to use implicit differentiation to find a 2nd derivative of an equation.

This video uses a second degree equation with variables x and y as the starting point of the example. Subsequently, the presenter finds the second derivative of the equation in terms of x, y and (dy/dx) in the first half. In the second half of the video, the presenter then proceeds and finds the answer in terms of y using the intermediate results obtained, and then using a few basic maneuvers of differentiation and basic equation-solving.
