Section 2.5: Derivatives of Quotients
Key Concepts:
You are expected to be able to differentiate simple quotient functions with and without using the Quotient Rule. To differentiate simple quotient functions without the Quotient Rule, you first have to rewrite the simple quotient functions as a product of two functions, one of which has a negative exponent (the denominator), then differentiate with both the Chain Rule and Product Rule.
