This program is designed to plot graphs of mathematical functions. It enables to insert and select up to seven functions and plot them. You can trace function's values and pan/zoom the graph window.
I made this program as a homework for some subject in the first year at university. An old Pascal language was taught at those days. So this program is created in Borland Turbo Pascal IDE. Although this program is designed for MS-DOS operating system, it can run under MS Windows too. Maybe on newer 64-bit system you will need some kind of DOS emulator e.g. DOSBox.
