Desmos Graphing Calculator Status

Add sliders to demonstrate function transformations, create tables to input and plot data, animate your graphs, and more—all for free.  Accessibility: Read and edit math using a screen reader or a refreshable Braille display, and use audio trace to explore graphs and data through sound.  Tables: Input and plot data, or create an input-output table for any function.  Graphing: Plot polar, cartesian, or parametric graphs.  Plot any equation, from lines and parabolas to derivatives and Fourier series.  Zooming: Scale the axes independently or at the same time with the pinch of two fingers, or edit the window size manually to get the perfect window.  Sliders: Adjust values interactively to build intuition, or animate any parameter to visualize its effect on the graph.  Scientific Calculator: Just type in any equation you want to solve and Desmos will show you the answer.  Points of Interest: Touch a curve to show maximums, minimums, and points of intersection.  There’s no limit to how many expressions you can graph at one time—and you don’t even need to enter expressions in y= form!  Inequalities: Plot Cartesian and polar inequalities.  Explore math with the fast and powerful Desmos Graphing Calculator.  Hold and drag along a curve to see the coordinates change under your finger.  Tap the gray points of interest to see their coordinates.  Statistics: Find best-fit lines, parabolas, and more.  It can handle square roots, logs, absolute value, and more.
