Simple Grapher

Simple Grapher is a computer program to graph mathematical functions in two and three dimensions, and to carry out operations such as determining the derivative. The program, available free of charge, was developed by Brwa Hussen for educational and other purposes.^[1][2]

Sets of values or mathematical functions can be plotted. The application includes tools to help in producing plots.

A basic calculator, function evaluator and triangle, integral, derivative and composite solvers, and a 3D viewer are included. Color, transparency, and plot range can be specified. The plotted image can be saved in PNG, BMP or JPG format.

History

Simple Grapher V1.2 Screenshot

Simple Grapher was released in 2013, it was very simple (that is why named Simple Grapher) and had very simple features (plotting functions and simple inequalities), it also had a very bad GUI. But in few next versions it grow very fast and the program could support lot of features, and in November 2015 the program changed its name to Simple Grapher Plus, because it became very developed program and had a completely new interface.

In November 2015 the program was renamed Simple Grapher Plus, with changes to functionality and interface.
