Lesson #61 L'Hôpital's Rule

Quote of the Day: 
"Mathematics, in one view, is the science of infinity."  
      -- P. Davis and R. Hersh

Objectives:
The student will solve apply L'Hôpital's Rule to limit problems.
       
1. Collect homework.  

2. L'Hôpital's Rule is a method for finding limits of functions
      which evaluate to 0/0.

       

3. Comments: 
   (A) If f'(a) = g'(a) = 0,
       Then we may apply L'Hopital's Rule again.
   
   (B) NOTE: L'Hopital's Rule does NOT apply if
             either the numerator or denominator
             is NOT equal to 0.
