Tutorial:
For those, who do not understand my "clear" description in the .DOC file,
here is a short Tutorial:
Let's say you want to plot the function sin(x)*cos(1.5*x) and discuss it.
- Start the Plotter or you get problems to do the next things.
- You should see a blue screen. Use the mouse to look at the menus. You
should find a menu "change" with 10 subitems. There are some predefined
function. Select one. A window appears with a stringgadget. In this
stringgadget there should be the function you selected before. Delete it
and enter your new function. Remember: always lower case ! Press RETURN.
The Window should disappear, otherwise you should check, whether you have
closed all brackets again...
- Look at the menu Change again. There should be your new function now (or
the first 14 characters of it) instead of the old function. If you now go
on the menu "Function", the same subitems appear. Select your function.
- The function should appear on the screen. GREAT ! But you see that the
function is never greater than 0.91 or so. So select the menu Intervall.
Enter for ymin -0.91 and for ymax 0.91. After klicking on OK your old
function disappears. Let it plot again (Select Function/yourfunction). Now
it is better, isn't it ?
- Now discuss your function: Select Discussion/yourfunction. The function
disappears and a message appears that the function is discussed for the
intervall -3.141|3.141.
- The program will find 5 points where the function is zero, 6 extremas
(Min/Max) and 5 turning points. And the first and second differentiations
are displayed.
- To quit the program, select Quit. A requester appears to ask you, whether
you really want to quit. Select Quit.
