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. Shareware. Uploaded by the author.
