\begin{equation}...\end{equation} (\begin{equation*}...\end{equation*}) 最常用的标准的公式环境,表示一个公式,默认情况下表示一个单行的公式,但是它的功能可以通过内嵌各种其他环境进行扩展。 \begin{equation} \label{1-1} \frac{a}{b}\pm \frac{\int \frac{1}{\sqrt{1-x^{2}}}\mathrm{d}...
在使用LaTeX编写数学公式时，许多人会疑惑在方程组前或后是否需要空行。答案是不需要。LaTeX是用于排版和表示数学公式的强大工具。在编写方程组时，通常使用`align`或`equation`环境。以您提供的示例为例，该代码表示以下方程组：\begin{equation} \left{ \begin{array}{lr} a=2-b-c \ 2b=\frac{6...
\begin{equation} \left\{ \begin{aligned} a+b&=2\\ a-b&=4\\ \end{aligned} \right. \end{equation} 另外,还有其他方法,参考如下: \begin{equation} \left\{ \begin{array}{l} a+b=2\\ a-b=4\\ \end{array} \right. \end{equation} \begin{equation} \begin{cases} a+b=2\\ a-b...
