Cross-references in LaTeX

Mark any numbered element with a \label and refer to it later with \ref. LaTeX fills in the right number even after you reorder figures. The prefixes fig:, tab: and eq: help keep labels apart.

The results are listed in Table~\ref{tab:pendulum}, and Figure~\ref{fig:chart} on page~\pageref{fig:chart} shows the trend.

Common mistakes

• "??" in the PDF: references are only filled in on the second compilation.
• A normal space before \ref: the number can wrap to the next line. A tilde ~ keeps it attached.
