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.

App specific feature requests

This app has a very intuitive and quick user interface. It is very easy to input variable names due to the automatic subscript of numbers. However, there are a few simple improvements I believe would add convenience and usability.

1. Copy-paste functionality. There are many times where we have to use parts of equations which aren’t defined as functions. Copy pasting would make much more sense then retyping everything.

2. Ability to scroll left and right in large inputs. Currently, for inputs larger than the input area, we have to manually click the right arrow until we reach the end. It would be much better if we can “scroll” long inputs.

3. Multiple colours for lists. Currently, if you use lists like in the curve stitching example, all the generated outputs will be in the same colour.

Awesome 5 star app rater ,

My math teacher loves it

She has it on her phone, desktop
and probably on her laptop too.
Well i can say its quite useful
And its free which is good too.
You can create beautiful parabolas

Excellent App!

Does everything I need and more! Graphs everything from exponentials to logarithms! Lovely interface too
