# Grapher Pro - Equation Plotter & Solver

Everyone
67
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

Curve types
• Function (e.g. parabola, sine wave)
• Polar (e.g. rose, spiral)
• Parametric (e.g. ellipse, Lissajous) on the xy-plane or complex 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
• 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
• 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.
Note: Complex equation solving will be supported soon in a next update.

## What's New

• Tracing now shows a tangent line
• Inputs are now shown on graph captures
• Added hyperbolic secant functions (sech, csch, argsech, argcsch)
• Complex functions can now be plotted as a magnitude/phase pair
• Fixed math parsing bugs
• More performance and UI improvements
