Описание Grapher - Equation Plotter & Solver

Site Editorial Commentary：An extensive yet lightweight math graphing calculator.

grapher is a fast and effective equation plotter designed to effortlessly Draw any function, solve equations, and calculate expressions. Tailored for students, teachers, and engineers, this app offers a wide array of predefined functions, including trigonometric and hyperbolic functions, polar coordinates, differentiation, and more. The powerful math engine instantly processes and displays your input in both 2D and 3D modes. Functions can reference each other by name, enabling complex relationships and analyses.

We value your feedback and bug reports as we strive to make Grapher fit your needs. This free version offers a robust set of features. Consider upgrading to Grapher Pro to unlock awesome extensions, such as parameter sliders and complex plotting capabilities!

**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)

**Key Features:**
• Equation solver (numerical) for finding solutions to equations.
• Root finding, extrema detection, and intersection analysis with other functions.
• Inter-function referencing (e.g., g(x) = 2*f(x+1)).
• Custom math keyboard for easy input.
• Automatic input type detection.
• User variable support for both numbers and functions.
• Adjustable parameter range for cartesian, polar, and parametric curves.
• Input history for easy access to previous expressions.
• Plot up to 28 graphs simultaneously for comparative analysis.
• Differentiation (numerical) for calculus operations.
• Graph tracing for detailed analysis of plotted functions.
• Screenshot capture for easy sharing and documentation.

*note:* Mathematical functions should be entered using their names, such as sqrt(x) for √x. Long-press a key to see a list of available functions starting with that letter. Consult the 'Help' page for detailed explanations and a summary of all features.
