Desmos Graphing Calculator 4+


    • Free



Explore 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.


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.

Best Graphing App

As a student, I used this app often for quadratics optimization. It is completely free with all the important features, and works across all devices. The only technical complaint is that it logs you out every time you reboot your device. Additionally, while it is not entirely its fault, I failed my quadratic regression unit test because I used ‘=‘ instead of ‘~’. If only it showed me what went wrong like a spell check...

I have used Desmos since Grade 9, and absolutely love it. From being able to map out reciprocal functions to derivatives, it helps me understand the concepts so much better.

I would definitely recommend.

Musty app

This app is on something how tf x=5 go on 3.5 and not 5 where 3.5 come from mf 🤨🤨 pushed my pet fish off the stairs too rip Deshawn 😔💔
