List of commonly used mathematical symbols in LaTeX

LaTeX is a high-quality typesetting system that is particularly suitable for generating complex mathematical formulas. Here are some commonly used LaTeX mathematical symbols and their usage methods. Please note that these examples are typically used in mathematical modes, which can be intra row mathematical modes (such as $... $or $(... \)) or display mathematical modes (such as $[... ] or $$... $$).

Basic symbols

  • Addition, subtraction, multiplication, and division: +, - `` \times, \div

  • Example:$ a + b$, c×d

  • equals or does not equal: =`` \neq, \approx, \equiv

  • Example:$ x = y$, $a \neq b$, $c \approx d$, $e \equiv f$

  • Less than greater than: <, >`` \leq, \geq

  • Example:$ a < b$, $c > d$, $e \leq f$, $g \geq h$

Superscripts and subscripts

  • Use '^' to represent superscripts and '_' to represent subscripts
  • Example:$ x^2$, $y_i$, $z^{i+1}_j$

Score

  • Use \ frac {numerator} {denominator}}
  • Example:$ \frac{a}{b}$

Root number

  • Use '\ sqrt [root exponent] {square root}', omitting the root exponent defaults to square root
  • Example:$ \sqrt{x}$, $\sqrt[3]{y}$

Sum up, integral

  • Seeking peace: \Sum_ {Lower Limit} ^ {Upper Limit}
  • Example:$ \sum_{i=1}^{n} x_i$
  • Points: \Int_ {Lower Limit} ^ {Upper Limit}
  • Example:$ \int_{a}^{b} f(x) dx$

Matrix

-Using the Matrix environment -Example:

\[
\begin{matrix}
a & b \\
c & d
\end{matrix}
\]

-For different types of parentheses, 'pmatrix' can be used` BMatrix, Bmatrix, VMatrix, Vmatrix and other environments are used to replace Matrix.

Greek alphabet

  • Lowercase Greek letters start with a back slash followed by the letter name, for example, '\ alpha' \beta
  • The first letter of a capital Greek letter is capitalized, such as' Gamma ' \Delta
  • Example:$ \alpha$, $ \beta$, $ \Gamma$, $ \Delta$

###Relationship symbol

  • \in, \notin, \subset, \supset, \subseteq, \supseteq
  • Example:$ x \in A$, $y \notin B$, $C \subset D$, $E \supset F$, $G \subseteq H$, $I \supseteq J$

Special symbols

  • \infty, \partial, \nabla
  • Example:$ \infty$, $ \partial x$, $ \nabla f$

Arrow

  • \leftarrow, \rightarrow, \leftrightarrow, \uparrow, \downarrow, \updownarrow -Example:$ A \leftarrow B$, $C \rightarrow D$, $E \leftrightarrow F$, $G \uparrow H$, $I \downarrow J$, $K \updownarrow L$

This is just a part of LaTeX mathematical notation. As needed, it may be necessary to learn more commands and techniques. For more detailed lists and explanations, it is recommended to consult professional LaTeX reference manuals or online resources.
