Lesson #99 The Fundamental Theorem of Calculus
and Properties of the Definite Integral

Quote of the Day:
"It is clear that Economics, if it is to be a science at 
   all, must be a mathematical science ... simply because 
   it deals with quantities... 
   As the complete theory of almost every other science 
   involves the use of calculus, so we cannot have a true 
   theory of Economics without its aid." 
      -- W. S. Jevons

2. The Fundamental Theorem of Calculus 
      Each branch of mathematics has a fundamental theorem 
      associated with it.

      The Fundamental Theorem of Arithmetic:
        Any positive integer can be represented in exactly 
        one way as a product of primes.

      The Fundamental Theorem of Algebra:
        Every polynomial of degree n has exactly n zeroes. 

      The Fundamental Theorem of Geometry:
        No theorem wears this title, but perhaps the 
        Pythagorean Theorem deserves it.

      The Fundamental Theorem of Calculus – there are 
        actually two parts to this theorem:

        The First Fundamental Theorem of Calculus:
          The derivative of the integral of a function
            is equal to the function.
 
        The Second Fundamental Theorem of Calculus:
          The integral of the derivative of a function is  
            is equal to the function evaluated at its 
            endpoints.

   The F.T.C. tells us that we can evaluate a definite 
      integral by taking an indefinite integral and 
      substituting in the endpoints and taking the 
      difference:
