 It is a Java applet to serve as graphic calculator, equation
solver, plotter of user-defined functions, derivatives and integrals.
 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.
 For solving a system of equations, type an equation into the
y field, click on the "Graph" and "y" menu, then type another equation
over the y field, click on the "Graph" and "y" menu. The solutions are
the cross of these curves.
 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 in your hard disk. Please
let me know if you want to order your own copy to run in your hard disk.
