vmath2.zip      Online graphic calculator and symbolic math

Visual Math For Java 2 is graphic calculator, equation solver, plotter
of user-defined functions and data.  It is symbolic math and computer
algebra system, powered by SymbMath.

For calculation, users type expressions into the y field or click on the
LIST of functions, then click on the "=" button.

For evaluation of a function sin(x), first input sin(x) into the y
field, then input the x value into the "x=" field, finally click the "="
button to get the function value.

For solving an equation sin(x)=0, type the left side of the equation
sin(x) into the y field, click on the "solve" menu to get a solution at
the "x=" field.

For plotting functions, click on the "Graph" and "y", "Zoom In" or "Zoom
Out" menu.  For plotting first-order of derivative, click on the "dy/dx"
menu.  For second-order of derivative, click on the "dy/dx" menu again.
For plotting its integral, click on the "Integrate" menu.

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

You can copy-and-paste the text field 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).

If you see it online, it can run off-line in your computer.  You need
password to logon under Help menu to activate some menus.

For security reasons, Open and Save files, and Print work only when it
runs as local application.  Its symbolic math works only when it runs in
MS Window.

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.

Special requirements: Java 1.1 runtime.

Changes: Additional features added.
