Looking for a simple tool that would do the tedious task of drawing mathematical functions for you? Help is on the way - FNGraph. FNGraph is a tool that allows you to draw functions with ease. All you have to do is type in your function (for example, 2*x+1) and hit the OK button. There it is - the graph is ready right away. It also allows you to calculate values of functions - just type it in and get the results. The help file contents is not much help actually, but at least it contains a full list of supported functions (from sin(x) to ln(x)), some advice on expressions syntax and a few examples. FNGraph does not have any particular requirements regarding hardware. You can run several files simultaneously and arrange them appropriately on the screen. You can also print out graphs and draw several graphs on one grid - that is useful when you want to compare functions.
