### App Description

```At Desmos, we imagine a world of universal math literacy and envision a world where maths 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 maths 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 maths. 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 grey 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.

### Reviews From google play store

The app is great and useful. There is one bug though where when you change the name of any folder a blank white screen appears and blocks around 40% of the view for portrait (less for landscape) but is removable when typing into the equation section. It'd be better if I don't have to do it though. Another bug is that when moving an equation tab(?), sometimes it won't follow through. Those bugs aside, the app is great and easy to use.

its an awesome app very very very useful in visualizing and analyzing the graphs which are hard to imagine by simply seeing the equation. you can change the contants of any equation and see the effect like an animations... thats the killing edge of this app!! very useful for students who had a hard time solving numericals of calculus or geometry. All the best to the developing team and Hope to see similar amazing apps... :)

Oh My God... Genius are Here.... I m surprised why these were not available during our school days... Math is so interesting and fantastic..its just how we get prooer guidance... Many Many Thanx Demos.. i m fall in love with Math...with your support.

Awesome app but sometimes handling becomes difficult. It is difficult to swipe the equation in case equation is very long. Also many times axes get zoomed instead of whole graph. Hope it is solved soon!!! And yes it is the best no doubt and it makes me forget the odds. Good job :)

I really love this app since a friend of mine told me about its existence back in 2015. I encourage you to add some new features for a premium version (which I would buy regardless of the price). 1) Logarithmic scales for axis. 2) Settings can be saved for future sessions (Projector mode, radians or grades...) 3) A 3D grapher (with parameters that would make 3d shapes to move) would wake up terrific feelings inside all of us. We love your work in this app.

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!

The graphing was incorrect. I typed in the polynomial function f(x)=x^4 + 4x^2 + 16 and it gave me a very thin, very quadratic parabola. So much for helping me find the roots of the polynomial...

I first came to know about Dedmos from a Quanta Magazine article about 4 years ago. It's really awesome. Whenever I have to see how a function looks like I use Desmos.

Some graphs are wrong. Especially those in which fractional part is involved. Also, It doesn't show which points are included in the graph and which aren't very clearly. Lastly, why the hell I need to login everytime I restart the app? Fix these in next update.

This app is really awesome. It's very useful for today's lifestyle. I'm a JAM student and this app helps me a lot to solve difficult questions by graphical approach 👌.

Really nice and the only best graphing tool available on play store. Now is the time to make to the best Plz add a seprate argand plane also where we can deal with complex no. (a real mathematician will only understand importance of graphing in argand plane) plz also add "fractional part of x" funtion also i need that

This calculator is soooo good, words can't describe how I feel. I'm in love with this calculator. My only gripes with it are the bugs where clicking on a line puts you one above, below, or somewhere else completely, not the line that was clicked on. The sine and cosine functions are also buggy when coming back to it to add to the function inside them.

This is a wonderful tool for when I don't have my Ti-inspire charged! the only thing I would love to have is a way to preset Degree as my primary mode, instead of radians.

Best app ever to learn mathematics. One can actually learn graphs from this app. Very high efforts have been taken to design this app. It's highly appreciated that such an application is given free of cost.

One of the best app to learn everything about graphs. Just type a function and the graph will appear. Appreciate the developers for adding different colours for different curves which makes it easier to understand the shape of the curve and intersection points. Great to see that they have included a slider option so that you can manually slide the constant value to see how the graph reacts. Great Job developers. You helped me grow interest in Math.

this is an awesome app, does everything I would need a graphics calculator for, is easy and user friendly, and best of all there's no ads. thank you very much

Desmos is a very useful app. I would recommend it to all students. Especially those studying Science and Engineering. However, I wish they would allow you to connect points from a table using a best fit line or curve or by just connecting all the points.

simply the best graphing calculator you can get. You won't find a calculator with a cleaner, or more user friendly interface.

Best graph calculator. I have tried several graph calculator to compare the local behavier of y²=x⁴-xy³ and y²=x⁴, and this is the only one which gives santisfactory result. Desmos is efficient and powerful. I like it so much as a math student. It would be better if it could calculate surface in 3D.

A good calculator, at first. Within three minutes, it crashed. Now I can't finish my homework. Yay.
