Hello
According to the system for managing to a mathematical equation, there is MAXIMA*.exe by MIT in USA and it is a free software.
http://maxima.sourceforge.net/
MAXIMA can easily execute an expansion, a factorization, a differential calculus, a integral calculus, solving an equation and drawing a 3-D graph.
Please download that system and use it.
My software is very simple and lower grade than that system.
If you will know a program structure of an elementary system according to managing for an expansion, please download my software.
About Equation software
In 1989 I made the software for making an expansion of an equation by N88-BASIC(NEC
Corporation). Now this software come back by F-BASICver6.3(Fujitu Corporation).
I used this software for the calculation according to the equation passing
several points on plane and having minimum distance from those points,
because these processes were very complicated.
This software is made for the purpose of acquiring the expanded result
of "-2a5b4d-2a5b2d+20a4b2c+20a4b4c-2a3b2d-2a3b4d-2a3b3-2a3b+20a2b4c+20a2b2c-2ab3-2ab",when
(20a2b2c-2a3b2d-2ab)(a2+1)(b2+1) is set.
Accordingly this software is made for the purpose of acquiring an expansion of an equation.
And the acquired equations can be added or expanded by working of files.
The straight line’s equation passing several points on XY-plane or 3-dimension and having minimum distance were showed on the document of "About equation software".
Now this software is v3.31. |
