Report an issueExplore math with the fast and powerful Desmos Graphing Calculator. Plot any equation, from lines and parabolas to derivatives and Fourier series. Add sliders to demonstrate function transformations, create tables to input and plot data, animate your graphs, and more—all for free.
Features:
Graphing: Plot polar, cartesian, or parametric graphs. 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!
Sliders: Adjust values interactively to build intuition, or animate any parameter to visualize its effect on the graph.
Tables: Input and plot data, or create an input-output table for any function.
Statistics: Find best-fit lines, parabolas, and more.
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.
Points of Interest: Touch a curve to show maximums, minimums, and points of intersection. Tap the gray points of interest to see their coordinates. Hold and drag along a curve to see the coordinates change under your finger.
Scientific Calculator: Just type in any equation you want to solve and Desmos will show you the answer. It can handle square roots, logs, absolute value, and more.
Inequalities: Plot Cartesian and polar inequalities. 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. Offline: No internet access required.

8 of 25hours of working day and night, it is straining my eyes. dark mode, please.
it’s good and yes there’s dark mode well it’s called color inversion and i get to make up my own formulas so it’s 5 stars.
Thank you
Awesome for algebra, especially you’re a visual person. Designed pretty well, too.
Taking off 1 star for attention. I love this app and use it often. I really would love to have app versions of your other products however - Four Function Tool, Matrix Tool, Geometry Calculator, and 3D Graphing Calculator. Using them on my laptop is less user friendly, in my experience.
I haven’t been in a math class in years but I am still using Desmos as my main calculator for everyday needs. The only bad thing about using Desmos is that it makes all other calculators feel awful to use.
How is this tool so good for being free? The developers did an amazing job on this app! You can even apply derivatives and integrals on functions, create polygons, make music (with multiple overtones to synthesize any sound), and so much more!
The core strength of the Desmos app is its speed and fluidity. On a traditional hardware calculator, plotting an equation requires navigating tedious menus and waiting for lines to render pixel-by-pixel. In Desmos, you type an expression, and it appears instantly on a highly responsive, pinch-to-zoom grid.
