Grapher Pro - Equation Plotter & Solver for Android

Grapher Pro is a fast and effective equation plotter, capable of drawing any function (including complex-valued ones), solving equations and calculating expressions. Especially if you're a student, teacher or engineer, this app is made with you in mind! A wide range of predefined functions is available, including trigonometric & hyperbolic functions, differentiation and more. Anything you type will be processed and displayed instantly by a powerful math engine, in both 2D and 3D modes. Furthermore, functions can reference each other and variable sliders allow for efficient visualization.

Grapher is continuously under development, with more features yet to come. Any feedback and bug-reports are greatly appreciated!

Note: Mathematical functions should be typed by their names, for example sqrt(x) means x. Hold a key to see all function names starting with that letter. If something is unclear, be sure to check out the 'Help' page as all details are summarized there.

Note: Complex equation solving will be supported soon in a next update.
