Grapher - Equation Plotter 1.4.4b

Grapher is a fast and effective equation plotter that is highly suitable for students, teachers, and engineers. It offers a wide range of capabilities such as drawing any function, solving equations, and calculating expressions. The application features a powerful math engine that instantly processes and displays anything you type in both 2D and 3D modes, allowing for seamless functionality. Additionally, functions can reference each other by name.

We value your feedback and bug-reports as we are committed to tailoring Grapher to meet your needs. While this free version provides most of the features, we encourage you to consider purchasing the Grapher Pro version for access to additional extensions like parameter sliders and complex plotting.

Curve types

• 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)

Additional 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, and parametric curves)
• Input history
• Plot up to 28 graphs simultaneously
• Differentiation (numerical)
• Trace graph
• Capture screenshots

Note: Mathematical functions should be typed using their names, for example, sqrt(x) means √x. To view all function names starting with a particular letter, hold down the corresponding key. If you need further clarification, please consult the 'Help' page which provides a summary of all the details.
