Lesson #94 Exact Area Under A Curve

Quote of the Day:
"Mathematics is not a deductive science – that's a cliché.  
   When you try to prove a theorem, you don't just list the 
   hypotheses, and then start to reason.  What you do is 
   trial and error, experimentation, guesswork."  
   -- Paul Halmos

Objectives:
The student will determine the area under a curve by 
   summing up rectangles and then taking a limit.

1. Collect Homework.

2. To determine the exact area under a curve, examine the
   diagrams below:

       
       
       
    Notice, as we increase the number of rectangles, we 
    get closer to the exact area under the curve.
