            ==================================

This  program  evaluates  definite  integrals  with  fixed 
limits,  by  the use of the 'trapezium rule'.  To use  the 
program, click on the icon on the icon bar to bring up the 
window,  and  then type the relevant function  and  limits 
into the spaces provided.  Press Return,  to calculate the 
integral of the function, to 4 significant figures.

The function and limits must be in a form that BASIC would 
accept, e.g.
                    3*x rather than 3x
                1/cos x rather than sec x
              (sin x)^2 rather than sinx
                  exp x rather than e^x 

Pi can be used in the function or limits - just type 'pi'.

Upper or lower case can be used throughout.

I  hope this explains everything.   If not,  feel free  to
