Mathematics

The mathematics powered by MathJax:

\[\begin{equation} \sum_{n=1}^\infty 1/n^2 = \frac{\pi^2}{6} \label{eq:series} \end{equation}\]

We can reference the equation as \eqref{eq:series}.

This sentence uses $ delimiters to show math inline: $\sqrt{3x-1}+(1+x)^2$

This sentence uses $` and `$ delimiters to show math inline: $\sqrt{3x-1}+(1+x)^2$

The following entry uses two dollar symbols $$ to delimit a math expression and render it as a block.

\[\left( \sum_{k=1}^n a_k b_k \right)^2 \leq \left( \sum_{k=1}^n a_k^2 \right) \left( \sum_{k=1}^n b_k^2 \right)\]

The following entry uses the ```math code block syntax to display a math expression as a block. With this syntax, you don’t need to use $$ delimiters.

\left( \sum_{k=1}^n a_k b_k \right)^2 \leq \left( \sum_{k=1}^n a_k^2 \right) \left( \sum_{k=1}^n b_k^2 \right)

This expression uses \$ to display a dollar sign: $\sqrt{\$4}$

To split $100 in half, we calculate $100/2$
