About Desmos Graphing Calculator

Desmos is the next generation of the graphing calculator. Desmos Graphing Calculator automatically solves and graphs equations for users. The calculator can plot a variety of different equations, from lines to parabolas and more. It can take a set of data and create a graph. It supports functions and inequalities; it can graph exponents and logs, trig functions, precalculus and calculus problems, and even statistics and probability. The uses of Desmos are unlimited in the math class. Desmos is a free graphing and teaching tool for math available on the web as well as on the App Store for iPhone, iPad and Google Play for Android.

Desmos Graphing Calculator Review

What's it about?

Desmos Graphing Calculator is an assistive tool designed to help you understand complex math concepts by graphing them to a coordinate plane (a graph with an x-axis and a y-axis). If you’re looking for a calculator app that is simple to use and delivers consistent results, this is a great choice.

How can students benefit?

With Desmos, students don't have to download anything, and they find that the online calculator is easier to use than the handheld or software, once they get past the initial learning curve.

How can teachers benefit?

Desmos can be used primarily by teachers for creating graphs to show students solutions to problems. Teachers can also give students this link so that they can check homework on their own. 

Desmos can used in teaching by giving the students certain practice problems containing linear equations to graph. The students can be asked to examine the graph and answer certain questions based on the graph. Students can able to see that a line can be the same even if the equation you are given looks different because it could be in a different form. This can be a great opener for the students to learn to translate lines from point-slope form to slope-intercept form, and finally to standard form. 

One of the easiest aspects of Desmos to use in the classroom is the slider feature. You will also be able to graph different relations and functions without having to navigate menus, and just using the keyboard. Finding zeros and intersections are really easy, though you wish Desmos would display more decimal places. Creating graphs to use on homework assignments and assessments is a lot easier to do with Desmos than with other software, as well - the images come out cleaner, and are relatively easy to crop or edit.

What are the benefits of Desmos?

Using Desmos as an embedded calculator in the testing environment creates a standardized and consistent testing platform as every student will be using the same calculator on the Standards of Learning assessment. Currently, a variety of different brands and types of calculators are approved for use on Standards of Learning assessments, and this requires school divisions and the Virginia Department of Education to regularly ensure that newly developed features are consistent, equitable, and fair for use on assessments. The transition to Desmos also will eliminate the testing irregularities that can occur when an appropriate approved device is not provided for testing or the device is not properly prepared for testing. 

The Desmos graphing calculator allows users to view and manipulate multiple representations simultaneously, promoting a deeper conceptual understanding of mathematics. Desmos has features that promote student inquiry and help students understand the rich connections and complexity of mathematics. Today’s students are connected to technology through the use of smartphones, tablets, and other devices. The ability to leverage Desmos as a form of instructional technology that melds into the current ways students are accessing information can translate to higher student engagement and meaningful math inquiry.

Desmos is currently available on assessments in a number of states and is now included as an embedded tool on the calculator portion of the new digital SAT, PSAT 10, and PSAT 8/9. The College Board has created a Student Digital Test Preview which includes the link to the Desmos graphing calculator, along with options for accessible testing features.

Should you download it?

If you’re looking for a calculator app that is simple to use and delivers consistent results, this is a great choice.

Is there a better alternative?

Although math solver apps, such as Mathway, WolframAlpha, deal with more complex problems, this app remains a great choice for anyone.

Explore math with Desmos! Plot functions, create tables, add sliders, animate your graphs, and more -- all for free.

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.


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. Try typing y=mx+b and adding sliders to get started.

Tables: Input and plot data, or create an input-output table for any function.

Statistics: Find best-fit lines, parabolas, and more.

Calculus: Graph derivatives (d/dx) and explore key concepts by building secant and tangent line sliders. Graph Maclaurin Series (okay, all kinds of Taylor Series, but that guy gets no love...) Evaluate a definite integral (int) in an instant, or plot an integral with varying bounds.

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.
