The app Desmos Graphing Calculator is made to help students understand advanced math concepts. The app does this by putting them onto a graph with an x-axis and y-axis, also called a coordinate plane. “The built-in examples cover subjects such as lines, parabolas, trigonometry, conic sections, parametric equations, transformations, statistics, lists, and calculus.” Students can change variables manually, graph several functions at once, and save/share their work.
