Grapher Pro - Equation Plotter & Solver for Android

Developer's Description

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!

Pro version features

Full support for complex 2D functions (i.e. plot a real + imaginary part) and complex plane parametric plots

Variable sliders: adjust parameters to see their effect in real-time

Choice between light and dark theme

No ads

Curve types

Function (e.g. parabola, sine wave)

3D parametric surface (e.g. sphere, hyperboloid)

More features

Equation solver (numerical)

Find roots, extrema and intersections with other functions

Complex number support

Real-time variable sliders

Functions can reference each other, e.g. g(x)=2*f(x+1)

Custom math keyboard

Auto-detect input type

User variable support for both numbers and functions

Adjustable parameter range (for cartesian, polar & parametric curves)

Input history

Plot up to 24 graphs at once

Light and dark theme

Differentiation (numerical)

Trace graph

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.
