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.
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.

I was in an incredibly bad period in my life. Everything was going horribly, and I even stared death in the face, until my maths teacher Mr Vlastos introduced me to Desmos. Since then, everything has changed for the better. I wake up in the mornings and remember that Desmos is there for me. There’s never a moment where Desmos is not on my mind. It’s smooth, silky graph lines never fail to bring a smile to my face. I love Desmos, and Desmos loves me.
Great but often loses data

I use Desmos often on desktop and while it’s one of the better graphics calculators out there on iOS I often lose my work - if I change context and change back to Desmos after a few minutes, more often than not, everything is wiped as the operating system closes the app in the background. This is always unexpected, especially since I’m logged inWould be great if the state is saved, even just to some untitled file so I can recover my work when the app closes
Have faith... believe in desmos

Uncle des really helped me through a tough time: quadratics. I highly recommend bcs he’s an actual G. He’s a reliable source of happiness and I trust him with all my secrets. I utterly have too many words to describe how great Uncle Des is. He helped me through life when it was tough and I felt like I couldn’t go on. Desmos was the light of my life and overall really improved my drama grades. I LOVE YOU

As a kid i used to save up my pocket money to by graph paper and 3H pencils , to plot graphs, and explore the wonders of finctions on the cartesian plane.The school did have an apple 2 computer somewhere, with 5.25 inch floppies but that really didn’t help. The dot matrix really wasnt set up to print graphics, unless you coded your own programme in assembler for the 6502Nowadays Desmos does it all . joy!!!
