Grapher is a fast and effective equation plotter, capable of drawing any function, 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, polar coordinates, 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 by their name.

As I strive to make Grapher fit your needs, any feedback and bug-reports are greatly appreciated. This free version is ad-supported; please consider buying Grapher Pro to remove all ads and enjoy extra features!

Function (e.g. parabola, sine wave)
Polar (e.g. rose, spiral)
Parametric (e.g. ellipse, Lissajous) on the xy-plane or rθ-plane
Implicit equation (e.g. conic sections)
Implicit inequality (e.g. half-plane)
• 3D function (e.g. paraboloid)
• 3D parametric curve (e.g. helix)
• 3D parametric surface (e.g. sphere, hyperboloid)

More features
Equation solver (numerical)
Find roots, extrema and intersections with other functions
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 28 graphs at once
Differentiation (numerical)
Trace graph
Capture screenshots

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.
