Staff Review
This lesson is a great introduction to implicit differentiation. Several great, complete examples are used, including the equation for an ellipse, and the equation x^3 * y^2 = x * y^3 + 6. Also, in a related topic, you learn how to find dy/dx when y = x^(1/n). You will learn how the power rule works for rational exponents. Some of the examples get pretty long and involved.
