Supported TeX/LaTeX commands

This is a long list of the TeX macros supported by MathJax. If the macro is defined in an extension, the name of the extension follows the macro name. If the extension is in brackets, the extension will be loaded automatically when the macro or environment is first used.

More complete details about how to use these macros, with examples and explanations, is available at Carol Fisher’s TeX Commands Available in MathJax page. (These were written for MathJax v2, but most of the information is still correct for v3.)

In the following tables, the first column lists the macro (or character, or environment), and the second column indicates which package(s) defines the macro. If none is listed, then it is in the base package. If the package name is in bold, then it is preloaded by the components that include the TeX input jax (except for input/tex-base, which only includes the base package). If the package name is in italics, then the package is not autoloaded by the autoload extension.

Note that most macros are not processed inside text-mode material (such as that within \text{} and other similar macros). The textmacros extension makes additional macros available in text mode, as listed in the documentation for that extention.

3.1. 创建TeX对象

▶️运行示例代码

✍️LaTeX公式编辑器

TeX表达式内容创建SVG图像。

TeX表达式如下所示:

\overrightarrow{F}_{12} = k_e \frac{q_1 q_2}{r^2}

4. 函数图像

🔗2DGraph

4.1. 创建函数图像

以函数f(x)创建出SVG图像。在数学中,函数 f 的图形(或图像)指的是所有有序数对(xf(x))组成的集合。

第一个参数是一个匿名函数对象。设该函数的形参为x,输入值范围在(-10,10)之间,返回值代表图像的y坐标,返回值在(-10,10)之间。

4.2. 创建极坐标图像

极坐标系是一个二维坐标系统,该坐标系统中任意位置可由一个夹角和一段相对原点—极点的距离来表示。极坐标图(Polar)用来将极坐标系的信息表示出来的图形格式。
