This tutorial shall help you to use MathPlot the first time.


Introduction
============ 
 You want to try MathPlot. I try to help you: 
 Let's say, you want to plot the following functions:
  sin(x)+cos(x)
  2*sin(x)
  sin(2*x)
 As intervall, you want [-\pi,\pi].
 
Preparation
===========
 Make sure that you have the following files in LIBS:
 
 - mathieeedoubbas.library
 - mathieeedoubtrans.library
 - asl.library
 - mtool.library
 - diskfont.library (V36 or higher)

 If you work often with MathPlot, copy the following files to S:

 - mplot.prefs
 - Funktionen.fkt
 - Konstanten.con
 - Macros.mcr

 Start MathPlot with a double-click.

Enter your preferences
======================
 If you have not the file "mplot.prefs" in S:, a requesters appears. Just
 click on OK.
 You should first enter your prefered settings. E.g. use 
 Preferences/Resolution to set your prefered screenmode. Use "Use" to
 see a result. Save your preferences to s:mplot.prefs and restart MathPlot
 (or use "Use").
 
Enter the functions
===================
 Well, the three functions are quite short, but to make clear how to use it,
 use the macros:
 
Enter the macros
================
 Select the item Macros. A window should appear with two gadgets. Press
 the key a. An a$ should appear in the first gadget. Press RETURN.
 In the second gadget, enter sin(x) and press RETURN.
 Select Macros again. Enter b and cos(x).
 
Enter the functions
===================
 Now you can enter the functions. Select three subitems of the item Change.
 A window should appear with a gadget. If there is already some text, 
 delete it with right-Amiga-x. Then enter _a+_b. Press RETURN. The window 
 disappears and appears right again. Enter the second function (that is 
 2*_a). After RETURN, you can enter the last function (that is _a(2*x)).
 If you look at the subitem of Change, you should see your functions.

Enter the intervall
===================
 Select Intervall. Enter for x-min -pi, for x-max pi, for y-min -20 and for 
 y-max 20. Both cyclegadgets should be *1.
 
Plot the functions
==================
 Select at Function/... your three functions. They will be plotted. You
 will see, that -20/20 was too much.
 
Change the intervall
====================
 You could select Intervall and change it. But you can also use the mouse: 
 Select Zoom, select one corner of your new intervall, move the mouse and 
 select the second corner. The screen should be cleared.
 
Plot axis
=========
 Choose Axis/autom.. As colour, choose i.e. 3. Now you are ready.
