# Description

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.

Wow, it's fantastic. This is so quick and intuitive to use on my large Samsung tablet. Although I have installed it on my phone too, it is rather difficult to use the small sliders there; but perhaps my thumb is too big. The associated web site has many excellent articles to explain how to get the most out of the app.

This is such a great app to help with teaching maths. I can't recommend it enough for learning about and or just picturing what straight lines, quadratics, trig etc look like. Well done and thank you Desmos

Awesome graphing calculator. Can't believe it's free! Not having to enter equations in "y=" form is convenient for checking homework. Good job developers!

The only graphing calculator which I like much more than that of Mathlab's Graphing Calculator but please add more functions please like that of MATLAB so that DESMOS can become the best. It is better than Geogebra's Graphing Calculator too. And at last it's better than any because it's free!!! LoL

The new version has more bugs than the older one.sometimes it doesn't show complete graphs.its not showing the complete graph for the function (x+1)÷(a+x^2) where is any constant.also for (sin^2(x) +sinx -1)÷( sin^2(x) -sinx+2) the graph is incomplete

All of the data goes away whenever I switch apps. I have to keep entering the data. Someone should seriously fix this

Sorry! Can you give an example of a graph that hangs? Which version were you on before? It cannot represent a few equations grafically , otherwise it's a marvelous app.

Desmos Inc April 17, 2017

Which equations can it not represent? Email support@desmos.com -- hopefully we can help! A very fantastic app, it could have been better if the user have the option to enter the range in which graph is to be sketched; and also if we could extract the values at any point.

Try typing something like y=2x-1 {0 < x < 3}
That will give you a restricted range. If you click and drag on a curve, it'll show you the values at that point. The best graphing calculator out there! I've been through about five different graphing calculators and this is by far the best. I don't think I'll be going through any more any time soon.

It's a great graphing program with many useful features. And the play function on sliders is very useful. Just put in a wave equation and play the time variable and enjoy!

Amazing app. Great job guys! Thank you for developing this free app for all specially Math students & their parents :) 2 thumbs up!

Sliders are not working on android. They play fine but I can't move them . Now it is fixed .Thanks. here is my 5 star

I Really like the app but I wish I could scroll the table to see more values without having to replace them

It's the best mate out there for everything Math! My 5 stars convey the rest.

It's great but it would be nicer if it had steps the show you how you got the points and stuff

Desmos Inc April 17, 2017

Exponents should work! What are you trying? If you type something like: "x" and then the "a^b" button, and then "3", you'll get a graph of x^3. Email support@desmos.com if we can help out.
- Eli & Team Desmos I really like this app because it helped me a lot through my senior year. Yeah.

Awesome graph calculator, helps to establish a relation with graphs, a boon to mathematics lovers like me :)

Its a fantastic programming done by desmos, really hates off

It's really easy to use and can provide most of your needs. Well done
