latex常用符号总结
作者:互联网
常用的latex符号总结一下,方便下次查阅,每次都要baidu也挺麻烦。
1 常用公式
含义 | 符号 | 语法 |
---|---|---|
x y x^{y} xy | 上标 | x^{y} |
x 1 x_{1} x1 | 下标 | x_{1} |
∑ 1 n \sum_{1} ^{n} ∑1n | 求和 | \sum |
∏ 1 n \prod_{1} ^{n} ∏1n | 连乘 | \prod |
∫ 1 n \int_{1} ^{n} ∫1n | 积分 | \int |
⋂ \bigcap ⋂ | 交 | \bigcap |
⋃ \bigcup ⋃ | 并 | \bigcup |
x \sqrt{x} x | 开方 | \sqrt{x} |
x n \sqrt[n]{x} nx | n次方根 | \sqrt[n]{x} |
x y \frac{x}{y} yx | 分式 | \frac{x}{y} |
注: 求和符号若要写成: ∑ i = 1 n \sum_{i=1} ^{n} i=1∑n 需要使用两个 $$ \sum_{i=1} ^{n} $ $.
