Section 2.2: The Product Rule

Key Concepts:
Picture
Note: When given a function in factored form e.g. in the form of binomial products, the Product Rule is used to
           differentiate the function, instead of expanding the factors then differentiating the expanded form of the
           function using the Sum and/or the Difference Rule.


Lessons for Section 2.2:

The Product Rule
1. Proof of the Product Rule (a messy proof with colourful visuals)
2. Another Proof of the Product Rule (a more organized proof)
3. Common Mistake When Taking a Derivative of a Product (Pay attention and don't make this common mistake!)
4. The Derivatives of a Product IS NOT the Product of the Derivatives (You get warned once again!)

Applications of the Product Rule:
1. Differentiating Using the Product Rule (Example 1)
2. Differentiating Using the Product Rule (Example 2 - a challenging twist)
3. Differentiation Examples with Rational Exponents (Part 1)
4. Differentiation Examples with Rational Exponents (Part 2)
