          Four theorems below are not original but serve as a small reference guide indicating
          the usefulness of the Meijer G function to solving integration problems.  These
          theorems are very general since many special functions can be represented as
           Theorem. (Indefinite Integration.) 
           Theorem. (One G Function.) 
           
           where

          which appear in the last three theorems pertaining to definite integration.
