Graphmatica is a free-to-start equation plotting program from ksoft. The brainchild of University of California, Berkeley alumnus Keith Hertzer, this educational tool allows you to graph Cartesian and calculus-based mathematical statements for illustration and classroom-related activities. In contrast to the answer engine WolframAlpha, it only produces graphs for visual representation.

Versatile graphing

With Graphmatica, you can create graphic representations of a wide range of mathematical statements in various coordinate systems. The tool can handle Cartesian functions, relations, and inequalities, along with polar, parametric, and ordinary differential equations. Using these graphs, you can solve problems involving tangent lines, integrals, and algebraic functions.

For better comparison, you can even generate and display up to 999 graphs at the same time. Plus, you can refine your graphs with dozens of data-plotting and curve-fitting features and save them in various formats. The application boasts an intuitive user interface. Graphics-wise, it could use some upgrades.

Accessible math resource

All in all, Graphmatica stands out as a reliable, feature-rich graphing calculator that caters to a wide range of users, from students to professionals. Its extensive graphing capabilities, robust feature set, and straightforward design make it an excellent choice for anyone needing to visualize and analyze mathematical functions.
