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.
Offline: No internet access required.

정말 유용하게 쓰고 있습니다. - Awesome!
오류도 거의 없고, 최적화도 정말 잘 되어 있어 요긴하게 쓰고 있습니다. 한 가지 부탁이 있다면, 무리수 (e 혹은 루트 등등) 로 이루어진 좌표에 대해 (1,e)처럼 계산되기 전의 좌표를 표시해주는 기능이 추가되었으면 좋겠습니다.
There is no error and the optimization is really good! I can't stop using this app. Thank you for making this useful app, but I have a favor to ask of you - it would be more great if you add one function that shows coordinates that are not calculated. ex) (1,e)
THE BEST GRAPHING CALCULATOR
The best graphing calculator ive ever used.
