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 Left-Hand and Right-Hand 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. |
