Desmos Graphing Calculator

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.

Ratings and reviews

Before using the app here's some things to know: 1. You can't use your normal keyboard. They have an in app keyboard to use because it is appearntly extremely difficult to make normal keyboards work. 2. You can't copy and paste. For the same reason as the built in keyboard. 3. You can toggle whether you want to save a copy. I saw another reviewer confused why it always saved as a copy. There's a blue checkbox when you save. I LOVE DESMOS. I LOVE HOW FAST THE GRAPHS RUN ON MY PHONE

The app often zooms the UI to offscreen (the ability to scale the UI like it is a website wasn't fully disabled, leading to stuff like that on accident and the inability to undo) and I can't seem to share my graphs like I can on the website. Does allow you to use website functionality without an Internet connection, which is nice, although you won't be able to save.

Easily the best graphing calculator on the market, especially considering the cost (or lack thereof) and convenience of it being an app. **I am having an issue in which I can't log in via Google.** This aside, there is not one thing I dislike about this app, and I look forward to seeing what they will add next-- 3D app, anyone? I'd love to see a day in which Desmos wins the metaphorical war against TI.
