- Exponents and Subscripts: Exponents:
${x^i}$-> xi {x^i}xi 下标：${x_i}$-> x i {x_i} xi - Square root and nth root: Square root:
$\sqrt{x}$-> x \sqrt{x}x nth root:$\sqrt[n]{x}$-> xn \sqrt[n]{x}nx - Fraction:
$\frac{x}{y}$-> xy \frac{x}{y}yx - Vector representation:
$\vec{x}$-> x ⃗ \vec{x}x - Accumulation sign:
$\sum{x}$-> ∑ x \sum{x}∑x is used with subscripts and exponents:$\sum_{i=1}^n {x_i}$->∑ i = 1 nxi \sum_{i=1}^n{x_i}∑i=1nxi - Multiplication symbol:
$\prod{x}$-> ∏ x \prod{x}∏x is used with subscript and exponent:$\prod_{i=1}^n {x_i}$->∏ i = 1 nxi \prod_{i=1}^n{x_i}∏i=1nxi - Integral notation:
$\int{x}$-> ∫ x \int{x}∫x is used with subscripts and exponents:$\int_1^\pi {x}$->∫ 1 π x \int_1^\pi {x}∫1px - Left and right braces:
$\left({x^2+2*x+5} \right)^2$-> ( x 2 + 2 ∗ x + 5 ) 2 \left({x^2+2*x+5} \right)^2(x2+2∗x+5)2 is larger than normal brackets:$({x^2+2*x+5} )^2$->( x 2 + 2 ∗ x + 5 ) 2 ({x^2+2*x+5})^2(x2+2∗x+5)2 - Add a box:
$\boxed{x=1}$-> x = 1 \boxed{x=1}x=1 - Horizontal line:
$\overline{x+y}$-> x + y ‾ \overline{x+y}x+y$\underline{x+y}$-> x + y ‾ \underline{x+y} x+y
two examples
$\|X\|_p= \left({\sum_{i=1}^{n}{|x_i|^p}}\right)^{1/p}$-> ∥ X ∥ p = ( ∑ i = 1 n ∣ x i ∣ p ) 1 / p \| X \| _p= \left({\sum_{i=1}^{n}{|x_i|^p}}\right)^{1/p} ∥X∥p=(∑i=1n∣xi∣p)1/p$\boxed {\frac{1-e^{-2x}}{1+e^{-2x}}}$-> 1 − e − 2 x 1 + e − 2 x \boxed {\frac{1-e^{-2x}}{1+e^{-2x}}} 1+e−2x _ _1−e− 2 x
