MathPlanner 3.0.x Documentation
This is the main window of
MathPlanner 3.0. When you select an operator available options are
shown in "Operator Options" bar if there is any.
"Rat" button will set the function to use a Rational display
mode. There is many limitations in that mode but it could be useful sometimes.
Default setting can be changed from Configuration file.
Complex mode selector will set the layout of complex number. There is no effect in other types of
numbers.
Development
Main toolbar contains some unused buttons those are reserved for later features.
Graph support is removed from MathPlanner 3.0 becouse development process of core
functions is not yet finished. MathPlanner 3.1 or 3.2 should have those features up and running
again. Zoom features are not working well. It will be fixed with the other things related to the
paper space.
The main window:
Object selection, Insert Mode, Edit:
  |
Multible objects can be selected. By holding down the Shift-button
and pressing Left/Right-arrow keys. When more then one objects are
selected the insert mode is automaticly activated. Parenthesis will be automaticly assigned. |
 |
Insert mode is often required when writing functions. Insert mode can be activated by pressing insert-button. Insert mode will effect next keyboard or mouse input only. After that it will be deactivated. So. you have to turn it on every time when you use it. Here is some examples: First type "1" + "/"
+ "2" and Next example with the square root: "2" + "Alt+r"
|
 |
Be careful when
you are editing the functions. In some cases graphical layout may lie. It seems that "+2" is not inside the sigma operator but if you click the sigma object you will see that the blue rectangle is covering also "+2". So. Actual function is Sigma((3x/2)+2). This failure can be prevented by using "Par" (from operator options). But not from "Operator tool bar" |
"Rational" Display:
 |
"Rational" display may
be useful sometimes even if there is many limitations. Operational range
is quite short at this time but should be enough. Range with out the square root is 1...238 / 2...9999 Plus or minus can not be displayed. like: (2+Pi) / 3 Use the "Rat" button from main toolbar to turn this feature on and off. Default is on. Default setting can be changed from configuration file. This is a experimental feature |
Function Definations:
 |
After pressing Update button functions defined with "DefFN" are available in Function menu. "f" is predefined function that can be used in a cases shown below. There is no other usage for "f". Every modifier used in functions are local modifiers and are not effecting
to the global value of the modifier with the same name.
|
 |
|
Symbols:
 |
Greek symbols are available in
Symbol menu. Pii is predefined constant 3.1415.... the "Pi". Font setup must be defined correctly otherwice those symbols may look different. Fonts should have unicode charset. Some linux distributions may not contain font required to display special symbols. But there should be plenty in a internet. Basic fonts like Arial, Tahoma, Times New Roman should work fine. KCharSelector can be useful when looking for available fonts. |
Drag'n'Drop:
| Start draging objects by holding down left mouse button. You may move objects between applications. And you may drop files to the MathPlanner. Expecting that files are in *.html, *.xpm, *.png format. Also global copy-paste can be used between applications. But should no be used copy-paste inside MathPlanner. |
Configuration:
| Currently there is no better configuration available. But
should be in later versions 3.2. Configuration files are in two locations
/home/.MathPlanner/MPLConfig.txt and (usr/local or usr/X11R6) /share/MathPlanner/MPLConfig.txt.
File in a home folder is used first. If it is not existing the other file is used. |
Using Keyboard:
| Alt+r = Square root Alt+p = Power Alt+8 = Parenthesis Alt+i = Imaginary unit Alt+a = Complex angle Alt+e = e Alt+x = Exp Alt+l = Ln Alt+o = Log Alt+s = Sin Alt+c = Cos Alt+t = Tan |
