Description of Grapher Pro - Equation Plotter & Solver

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, 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 and variable sliders allow for efficient visualization.
As I strive to make Grapher fit your needs, any feedback and bug-reports are greatly appreciated!
Pro version features
• Full support for complex 2D functions (i.e. plot a real imaginary part), complex plane parametric plots and domain coloring
• Variable sliders: adjust parameters to see their effect in real-time
• Choice between light and dark theme
Curve types
• Function (e.g. parabola, sine wave)
• Polar (e.g. rose, spiral)
• Parametric (e.g. ellipse, Lissajous) on the xy-plane, rθ-plane or complex plane
• Implicit equation (e.g. conic sections)
• Implicit inequality (e.g. half-plane)
• Complex domain coloring (e.g. Riemann zeta)
• 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
• 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 28 graphs at once
• Light and dark theme
• 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.

  This is a really excellent equation plotter. I use it almost every day to give me a picture of functions I am exploring. It handles complex functions really well (needs pro version for that, and totally worth it). Only wish I had something similar for my PC.

  The Free version is absolutely perfect and got five stars. But the Pro version requires Internet connection for some strange reason. It displays a meaningless error message (something about "license check") and allows you only to Exit or Retry. Please disable this "license check" whatever that means. It is not a mathematical operation and should not be performed by scientific software. The whole point of installing a program locally is that you expect it to work without access to Internet.
