	It is an online symbolic math and computer algebra system. 
It can perform exact, numeric, symbolic and graphic computation, 
e.g. arbitrary-precision calculation, solve equation, plot data and 
user-defined functions, linear regression, symbolic differentation 
and integration, pattern-match. It is a programming language, in 
which you can define conditional, case, piecewise, recursive, 
multi-value functions and procedures, derivatives, integrals 
and rules.

	You have choice to run SymbMath  or SymbMath (DOS Edition)
engine. Their syntaxes are some different. Both syntaxes are 
case-sensitive. A first letter of keywords in SymbMath  
 is upper-case, but all keywords are lower case in SymbMath 
(DOS Edition).

	Please type expressions into the Input panel, or double- 
click on the Keyword panel, or click the Open menu to open a file.

	For evaluation of a function Exp(x), first input N(Exp(1)) 
into the Input panel, then click the Run menu to get the function 
value.
	
	For plotting functions, run Plot(x^2,x). Click on the "Zoom In" 
or "Zoom Out" menu under the Graph menu to zoom.

	For plotting data, click the Import Data menu to import data 
file. You can fit any function to data by comparing data and function
curves. Click the Linear Fit menu for linear regression.

	Find coordinates by clicking, get the initial value to 
the "x=" field by double-clicking, or zoom by drag, on graphics. 

	You can copy-and-paste from and to your document 
by right-button clicking on the text field to pop-up menu. For second 
way of copy-and-paste, first select the text, then key in Ctrl+C (i.e. 
press the Ctrl key and the C key at the same time), then point to where 
you want to paste, and finally key in Ctrl+V (i.e. press the Ctrl key 
and the V key at the same time).

	For security reason, Open and Save files, and Print work only 
when it runs as local application. Its SymbMath engine works only when
it runs in Microsoft Window. Please read SymbMath manual SymbMath.doc.

	If symbolic integration fails, you should add your integration
rules into the library file Int.vm in the vmath/library directory.

	You can develop your library, and save library files into the 
vmath/library directory. The library source codes are auto loaded 
when need. Please read document visualmath.doc or  visualmath.doc.htm.

	It runs in any computer, PDA, and mobile phone that supports Java™ technology. If you see it 
online, it can run offline in your computer, PDA, and mobile phone. 

	It is all of Java applet, Java application and Window 
application. Run VisualMath.html as Java applet, run VisualMath.bat as 
Java application, or run VisualMath.exe as Window application.

	It is assumed that you agree the Shareware license that you 
should register by US$19 with author after 20 days or you should 
delete it.
