Grapher Lite is another demonstration of the fact that math is fun. It is a simple function grapher that utilizes math functions to draw nice figures. In a single line, compose freely a series of at most 10 functions of a single variable (x), separated by a semi-colon “;” and press enter to plot them. You may then export the drawn figure to a PNG image file. The mathematical format used for expressing functions is similar to that used in spreadsheet applications. Only difference is that an expression like -x^2 is treated as (-x)^2 instead of -(x^2). It is recommended to employ braces to avoid confusion. Different standard math functions are included (please have a look at the list of math functions).
