Differentiation and Tangent Line Concepts

The video tutorial explains how to perform implicit differentiation to find dy/dx and determine the slope of the tangent line at a specific point. It covers the steps involved, including applying the chain and product rules, and solving for dy/dx. The tutorial concludes with evaluating the derivative at a given point and verifying the result graphically.

What is the first step in performing implicit differentiation?

When differentiating an expression involving y, what additional factor must be included?

• y/x

• dy/dx

• dx/dy

• x/y

Which rule is applied to find the derivative of e^(2xy) with respect to x?
