Desmos Graphing Calculator

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.

在假鹰爪，我们想象通用的数学素养的世界和想象的世界里，数学是方便和愉快的所有学生。我们认为，关键是边做边学。

为实现这一愿景，我们通过构建下一代图形计算器的开始。使用我们的强大和超炫快速的运算引擎，计算器可以立即绘制任何公式，从线和抛物线向上通过衍生品和傅里叶级数。滑块使一件轻而易举的展示功能的转换。这是直观的，美丽的数学。最重要的是：它是完全免费的。

产品特点：

制图：绘制极，笛卡尔，或参数图。有没有限制，你能有多少表现图表在同一时间 - 你甚至不需要在Y =表单中输入表情！

滑块：调整值交互方式建立的直觉，或动画任何参数的可视化图形上其效果

表：输入和绘图数据，或任何功能创建一个投入产出表

统计：查找最佳拟合直线，抛物线，等等。

缩放：缩放轴独立地或同时与两个手指捏，或手动编辑窗口大小，以获得完美的窗口。

景点：触摸曲线显示最大值路口，最小值和点。点击感兴趣的灰点看到自己的坐标。保持和沿曲线拖动，看坐标手指下更改。

科学计算器：只需输入你想解决什么方程和鹰爪会告诉你答案。它可以处理平方根，原木，绝对值等。

不等式：绘制直角坐标和极不平等。

离线：无需网络连接。
