About 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.

Frequently Asked Questions(FAQ)

What is Grapher Pro?

Grapher Pro is a fast and effective equation plotter, capable of drawing any function, solving equations, and calculating expressions. It is designed for students, teachers, and engineers, providing a wide range of predefined functions, including trigonometric and hyperbolic functions, polar coordinates, differentiation, and more. The app has a powerful math engine that can process and display functions instantly in both 2D and 3D modes, and it also supports variable sliders for efficient visualization.

What are the features of the Pro version of Grapher?

The Pro version of Grapher offers full support for complex 2D functions, complex plane parametric plots, and domain coloring. It includes variable sliders that allow users to adjust parameters and see their effect in real-time. The app also provides a choice between a light and dark theme.

What types of curves can be plotted using Grapher?

Grapher can plot various types of curves, including functions (such as parabolas and sine waves), polar curves (like roses and spirals), parametric curves (including ellipses and Lissajous figures) on different planes, implicit equations (such as conic sections), implicit inequalities (like half-planes), complex domain coloring (such as Riemann zeta functions), 3D functions (such as paraboloids), 3D parametric curves (like helixes), and 3D parametric surfaces (including spheres and hyperboloids).

What additional features does Grapher offer?

In addition to equation plotting, Grapher also includes an equation solver for numerical calculations. It can find roots, extrema, and intersections with other functions. The app supports complex numbers, real-time variable sliders, and the ability for functions to reference each other. It also provides a custom math keyboard, auto-detects input type, supports user-defined variables for both numbers and functions, allows adjustable parameter ranges for different curve types, and keeps an input history. Grapher can plot up to 28 graphs at once and offers both light and dark themes. Other features include numerical differentiation, graph tracing, and screenshot capture.

How should mathematical functions be typed in Grapher?

Mathematical functions in Grapher should be typed using their names. For example, sqrt(x) means the square root of x (√x). Users can hold a key to see all function names starting with that letter. If anything is unclear, the 'Help' page in the app provides a summary of all the details.
