Otherwise, use equation* (with an asterisk (*) symbol) if you need equations without the line number.. As shown in the example above, utilize the split environment if you would like to split the equations into smaller parts. \begin{align} \label{eq:lnnonspbb} \lambda_i + \mu_i = 0 \\ \mu_i \xi_i = 0 \\ \lambda_i [y_i (w^T x_i + b) - 1 + \xi_i] = 0 \end{align} only label the first equation and only the first equation can be referred later. It is also possible to set the tagging to ‘all’, so that every displayed equation will get a number, regardless of the environment used. Cases in Equations . List of LaTeX mathematical symbols.
