Easy to use intuitive program to visualize and study functions of one variable in a defined interval to find roots maxima and minima integral derivatives graph. You can predefine constants and specify the error bound for the results. It can fully explore intervals to search for solutions. Handles trigonometric and hyperbolic functions among others. Results including the graph can be saved or printed. You can also copy the graph to the clipboard which you can then paste where you please (Word Paint etc.). You have one-click control of the graph with zooming panning centering etc. Includes a help file with instructions example and methodology.
