Use the pair \lefts1 and \rights2 to match height of delimiters s1 and s2 to height of their contents, e.g.,

\left| expr \right| \left{ expr \right} \left\Vert expr \right.

4. 可变大小的符号(显示的公式显示更大的版本)

5. 标准函数名称

函数名称应该出现罗马字体,而不是倾斜,例如:

正确:\tan(at-n\pi) --> tan ⁡ ( a t − n π ) \tan(at-n\pi) tan(atnπ)

错误:tan(at-n\pi) --> t a n ( a t − n π ) tan(at-n\pi) tan(atnπ)
