Some useful commands for LaTex

Mathematical Symbols:

NOTE: always use the $(dollar) sign before and afer the expression when you are writing a mathematical expression in LaTex

Without $:

\geq

$\geq$ - the above statement but with the dollar sign added on both sides of the expression

---

Mathematical Symbols:

• $a^b$ is $a^b$ (exponents)
• $a_b$ is $a_b$ (subscript.. can be used to write chemical formulaes like $Ch_6$
• \frac{first arg}{second arg} is $\frac{first \space arg}{second \space arg}$ (fractions.. replace first arg and second arg by your expression)
• \neq is $\neq$ (not equals to.. can be used when a != b)
• \int is $\int$ ($\int$) or Integral Sign
• \lambda is $\lambda$ ($lambda) or Lambda
• \infty is $\infty$ or Infitnity
• \pi is $\pi$ or pi.. can be used to write the formula for circle's area($\pi r^2$)
• \sum is $\sum$ or Sumation

---

Misc Symbols:

• \circ is used to make a circle or degree symbol such as $180^{\circ}$ ($180^{\circ}$)
• \square is used to make a square.. like: $\square$
• \space is used to add spacing inside a mathematical expression.. $\int(x) \space + 1$ ($\int(x) \space + 1$)
• \rightarrow is $\rightarrow$ (Right Arrow)
• \leftarrow is $\leftarrow$ (Left Arrow)

Text Coloring:

NOTE: in order for colorization you must add package xcolor

Adding It:

\usepackage{xcolor}

---

Usage:

The available colors are black, blue, brown, cyan, darkgray, gray, green, lightgray, lime, magenta, olive, orange, pink, purple, red, teal, violet, white, yellow

\color{your_color}This is a colored text\color{white} % white is the FG here

Demo:

Code:

\usepackage {xcolor}
\color{red}This is a red text\color{white}
\color{orange}This is an orange text\color{white}
\color{yellow}This is a yellow text\color{white}
\color{green}This is a green text\color{white}
\color{blue}This is a blue text\color{white}
\color{purple}This is a purple text\color{white}

Preview:

$\color{red}This \space is \space a \space red \space text\color{white}$

$\color{orange}This \space is \space an \space orange \space text\color{white}$

$\color{yellow}This \space is \space a \space yellow \space text\color{white}$

$\color{green}This \space is \space a \space green \space text\color{white}$

$\color{blue}This \space is \space a \space blue \space text\color{white}$

$\color{purple}This \space is \space a \space purple \space text\color{white}$

Preamble

Your preamble is where you setup your LaTeX envioment and packages, often its imported from a spereate file called preamble.tex using the \input{} command.

Vectors

Creating vectors in LaTeX can be a hassle, use the folloing macros to make the process faster. This code introduces two new commands \vec{} and \pvec{}, \vec{ab} creates an arrow above your variable name like $\overrightarrow{ab}$ and \pvec{} creates a vector column such as \pvec{3 \\ 4 \\ 1}

Add the following code to your preamble after importing the amsmath (the amarecan mathmatical assosiation math package)

% Vectors
\renewcommand{\vec}[1]{\overrightarrow{#1}}

% Custom command for display vectors using pmatrix, use \pvec{1 \\ 2 \\ 3}
\newcommand{\pvec}[1]{%
  \begin{pmatrix}
  #1
  \end{pmatrix}%
}
