Graphmatica is an online graphing calculator app (or website) that helps students visualize, analyze, and explore mathematics. It allows users to plot any kind of equation or function, including parametric equations, polar equations, and 3D curves. It also allows users to graph multiple equations simultaneously, and to animate the graph by varying parameters in real-time. In addition, it has features such as interactive hints, a built-in error checker, and a step-by-step graphing tutorial. Graphmatica is a great tool for helping students understand complex mathematical equations and concepts.
