How to include and reference equations
This is video #12 in a series of twenty one by Dr Vincent Knight of Cardiff University.
In LaTeX we can label equations for easy reference within the article. Here we see how to create an equation using the \begin{equation} and \end{equation} commands. This equation is automatically numbered, and by including a \label command, we can refer to this number from anywhere within the rest of the document using the \ref command.
To try this for yourself, you can open the 'Equations' example (opens in a new tab/window) from the video. This can be edited online with writeLaTeX; you don't need to download or install anything to get started.
