Screen Shot

1) Start the program. The screen depicted at right will appear.
Press 'Enter'.


2) The next screen contains instructions, as shown at right. Press
'Enter'.


3) Enter the function after the 'F(X) = ' prompt, as shown. Press
'Enter'.


4) Prompts for upper and lower limits of integration appear, followed
by a prompt for the number of subdivisions to use in the calculation. (Use a bit
of caution here  selecting too high a subdivision count will result in an unacceptably
long delay. Just how big a count is too big varies with calculator model and user
mood.) Press 'Enter' after entering each value.


5) After a delay (the length of which depends on the number of
subdivisions calculated), the results are presented as at right. The LeftHand and
RightHand sums are at the top, followed by the Trapezoid Rule result and the difference
between it and the actual value, the Midpoint Rule result and it's error, and finally
the Simpson's Rule result and it's error. When you're ready to continue, press 'Enter'.


6) Press '2' at this point to quit, and the program exits. Pressing
'1' results in the next screen being presented.


7) Press '1' here and you can enter a new function; press '2' and
that step is skipped, and you are prompted for new limit and subdivision values.
