About this app

At Desmos, we imagine a world of universal math literacy and envision a world where math is accessible and enjoyable for all students. We believe the key is learning by doing.

To achieve this vision, we’ve started by building the next generation of the graphing calculator. Using our powerful and blazingly-fast math engine, the calculator can instantly plot any equation, from lines and parabolas up through derivatives and Fourier series. Sliders make it a breeze to demonstrate function transformations. It's intuitive, beautiful math. And best of all: it's completely 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.

Offline: No internet access required.

This app is really handy: it's powerful enough to use for basically any math class requiring graphing functions, and a lot of fun to play around with! There are some frustrating design oversights though. The most glaring to me being that you can't (or at least I can't) scroll longer functions to edit them, and it's basically impossible to tap the edge of it to bring it into view without deleting the whole thing. Besides little annoyances like that, it's great; I hope development continues!

Fantastic and incredibly useful. PLEASE change it back so that one can scroll laterally through an equation on a given line!! This makes plugging different numbers into the same formula so much easier! For longer formulas, when the end of the formula is off of the screen, and not being able to swipe to the end, there is a high probability of hitting the clear line (x) button when trying to plug new numbers in to the end of a given formula!!

I love this app. It's so very useful. For some reason, my expression list is vertically aligned, and it competes with my viewing window in such a narrow space. It didn't do that before, and I don't know why it changed, but I would definitely rate higher if I could switch it back to horizontally split with the viewing window.
