Lesson #23
Rules for Differentiation

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.

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:
