This powerful calculator allows you to draw up to six functions in a simple way. You write the function in a row just like writing on a paper. For exapmle: 'Sin X * X^2' and it will draw the function. The GraphicCalc can be used as a strong scientific calculator if you don`t use the 'X' in the function. You can even choose to draw the function`s derivative. Zooming in is done by selecting the desired area. You can choose the AutoZoom to fit the function to the screen. Clicking on the screen will show the function value for that point. This application is intended for anyone who loves math or wishes to understand it better.
