Grapher - graphing calculator

Grapher is a small, lightweight and useful graphing calculator and a function plotter for all pupils and students. The simple interface helps you to build any graph or function on a Cartesian coordinate system in just a few seconds. You can draw simple, parametric, polar or table types of math functions. You can build multiple functions with Grapher at the same time on the same screen using different colors. Grapher has the following features: * zooming and dragging * function list * color picker * simple interface * many standard functions * custom keyboard with all standard functions (like cos, sin, tg, sqrt, ln, log and so on) * different types of functions: * simple * parametric * polar * table * double tap zooming * thumbnails * more coming soon (aka graph generator, function grapher, math grapher, graphing calculator, function generator, math graph, graph plotter)
