Latex Mathematical Symbols

This article is completely transferred from the " common mathematical symbols LaTeX expression method ", reproduced in this only for easy access, I would like to pay tribute to the original author. LaTeX representation method of commonly used mathematical symbols

(The following is mainly excerpted from "a less brief introduction to Latex2e")

1, index and subscript can be used ^ and _ after the corresponding characters to achieve. Like what:

2. The input command for square root is: \sqrt,n The second root is correspondingly: \sqrt[n]. The size of the square root symbol is automatically adjusted by Latex. The \surd can also be used to give only
Symbol. Like what:

3. Command \overline and \underline to draw horizontal lines above and below the expression. Like what:

4. Command \overbrace and \underbrace give a horizontal curly brace above and below the expression.

5. Vectors (Vectors) are usually represented by variables with small arrows (arrow symbols) above. This can be obtained by \vec. The other two commands \overrightarrow and \overleftarrow are useful when defining vectors from A to B.

6. Score (fraction) use \frac{...} {...} Typesetting. In general, 1/2 is a more popular form because it looks better for a small fraction.

7, the integral operator (integral operator) is generated with \int. The sum operator (sum operator) is generated by \sum. The product operator (product operator) is generated by \prod. The upper and lower limits are generated with ^ and _, similar to superscript and subscript.

Here are some examples of how to represent common symbols
