Desmos Graphing Calculator

By Desmos

This app is only available on the App Store for iOS devices.

Description

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.

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. 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.

Offline: No internet access required.

What's New in Version 2.5.3

- Fixed a bug where equations that always evaluated to true or false were plotted as 1 or 0.
- User-defined labels can include interpolated constants.
- In order to better align with versions of Desmos apps used on high-stakes tests, solutions to single-variable equations are no longer displayed in the expressions list.
- Lists may be used as image coordinates, in which case one copy of the image is drawn for each list element.

Desmos Graphing App

I can quite easily say this is one of the most intuitive and beautifully designed apps I regularly use on my phone. I’ll admit, I don’t know how to use the vast majority of functions that Desmos can offer, but it does everything I could ever ask of it.

My only gripe (and it’s minor at that) is that I would prefer the radian coordinates to be given in terms of π on the axes.

Other than that, I wouldn’t change a thing!

so brilliant

Quite easily one of the best graphing apps on the app store and online. Does everything my graphing calculator does, without having to carry a huge brick around with me. I was searching for anything in app where I could pay because it’s just so good. Nothing. Nowhere in this app is there any sign or in-app purchasing. Beautifully designed and very easy to use. 5⭐️
