Implicit Differentiation Concepts and Techniques

The video tutorial explains implicit differentiation, focusing on differentiating the equation tangent of x over y equals x plus y. It covers applying the derivative to both sides, using the chain rule, and solving for dy/dx. The tutorial emphasizes understanding the chain rule and product rule, and concludes with algebraic manipulation to find the solution.

What is the first step in implicit differentiation?

• Solve for y explicitly.

• Apply the derivative operator to both sides of the equation.

• Integrate both sides of the equation.

• Use the product rule.

In the context of implicit differentiation, what does the chain rule help with?
