Quick guide to adding images.

%% Preamble

Placement

• Inline math formulas use \( \)
• Block math formulas use: \[ \]
• The package amsmath adds a lot of math functions and symbols.
• The package amssymb gives you access to a many more math symbols.

Math Symbols

A list of symbols I use often:

Math Snippets

Align

In block sections the align function is used to line up formulas horizontally. Each new line in the align block can have different anchor points, at &, &&, etc. These anchor points will match horizonally on each new line.

LaTeX:

\begin{align}
    f(x) & = x^2 + 4^x + 3 \\
         & = (x+3)(x+1)   && \text{factoring the polynomial} \\
         & && \{Now we can find the roots}
\end{align}

Output: \[ \begin{align} f(x) & = x^2 + 4^x + 3 \\ & = (x+3)(x+1) && \text{factoring the polynomial} \\ & && \text{Now we can find the roots} \end{align} \]

Piecewise Functions

LaTeX:

\usepackage{amsmath}
\[
    f(x) = \begin{cases}
        \frac{1}{2} \text{ $x$ is heads} \\
        \frac{1}{2} \text{ $x$ is tails}
    \end{cases}
\]

Output: \[ f(x) = \begin{cases} \frac{1}{2} \text{ $x$ is heads} \\ \frac{1}{2} \text{ $x$ is tails} \end{cases} \]
