Quote of the Day: "Although I am absolutely without training or knowledge in the exact sciences, I often seem to have more in common with mathematicians than with my fellow artists." -- M.C. Escher Objectives: The student will prove the power rule for derivatives. The student will apply the appropriate derivative formula to solving derivative problems. 1. Collect Homework. 2. Rules for Derivatives: Rule #1: Definition of the Derivative Rule #2: The derivative of a constant is zero. If f(x) = k Then f'(x) = 0. Draw a diagram to see this (interpret the derivative as slope). Rule #3: The Power Rule Proof: Rule #4: The Sum Rule Proof: Rule #5: The Difference Rule The proof is similar to the proof of the Sum Rule. 3. Examples: 4. Comic Strip about the Definition of the Derivative 5. Comic Strip regarding the Binomial Expansion
6. Higher-Order Derivatives (Second derivatives, …) To determine the second derivative, take the derivative of the first derivative. The notation for the second derivative: Examples: 7. Assignment: p. 196 (1, 3, 5, 9, 13, 15, 21, 37a,c, 39, 41a,b, 57) |
