LaTeX的主要优点之一是可以轻松地写出数学表达式。LaTeX允许两种编写数学表达式的模式: 内联模式和显示模式。第一个是用来写作为文本一部分的公式。第二种是用来写不属于文本或段落的表达式,因此放在单独的行中。
让我们看一个内联模式的例子:
In physics, the mass-energy equivalence is stated
by the equation $E=mc^2$, discovered in 1905 by Albert Einstein.

要使你的方程处于内联模式,请使用下列分隔符之一:
\(…\), $……$, \begin{math}…{math}结束。它们都有效,选择是一个品味问题。
($……$估计顺手一点,两眼发光的感觉)
显示模式有两个版本:编号和未编号。
The mass-energy equivalence is described by the famous equation
\[ E=mc^2 \]
discovered in 1905 by Albert Einstein.
In natural units ($c = 1$), the formula expresses the identity
\begin{equation}
E=m
\end{equation}

要在显示模式下打印方程,请使用以下分隔符之一:
\[…\], \{displaymath}……\end{displaymath}或者\begin{equation}…\end{equation}。
不建议使用$$……$$,因为它可能会给出不一致的间距,并且可能不适用于某些数学包。
注意:等式*环境是由外部包提供的,请参阅amsmath article
许多数学模式命令需要amsmath包,所以在编写数学时一定要包含它。下面显示了一些基本数学模式命令的示例。
Subscripts in math mode are written as $a_b$ and superscripts are written as $a^b$. These can be combined an nested to write expressions such as
\[ T^{i_1 i_2 \dots i_p}_{j_1 j_2 \dots j_q} = T(x^{i_1},\dots,x^{i_p},e_{j_1},\dots,e_{j_q}) \]
We write integrals using $\int$ and fractions using $\frac{a}{b}$. Limits are placed on integrals using superscripts and subscripts:
\[ \int_0^1 \frac{dx}{e^x} = \frac{e-1}{e} \]
Lower case Greek letters are written as $\omega$ $\delta$ etc. while upper case Greek letters are written as $\Omega$ $\Delta$.
Mathematical operators are prefixed with a backslash as $\sin(\beta)$, $\cos(\alpha)$, $\log(x)$ etc.
