• Inline Math (Use dollar signs)

The magnetic moment of a single spin is $\mu=\gamma I$

• Display Math (use double dollar signs)

To display math on its own line, use double dollar signs: $$ \frac{d}{dx}\left( \int_{0}^{x} f(u)\,du\right)=f(x) $$ or escaped square brackets: \[ \sin A \cos B = \frac{1}{2}\left[ \sin(A-B)+\sin(A+B) \right] \]

• A wide range of math environments

\begin{align*} e^x & = 1 + x + \frac{x^2}{2} + \frac{x^3}{6} + \cdots \\ & = \sum_{n\geq 0} \frac{x^n}{n!} \end{align*}
