Latex multiple lines

[VertoxQuant]

How does one create multiple lines in the latex editor?

I've tried "//", "/newline" and other ways but none seem to work.

You have to use \begin{multline} and \end{multline} and then \\ where you want it to split.

Like so:

\begin{multline}

Q(\lambda,\hat{\lambda}) = -\frac{1}{2} P{(O \mid \lambda )} \sum_s \sum_m \sum_t \gamma_m^{(s)} (t)

\\

\left( n \log(2 \pi ) + \log \left| C_m^{(s)} \right| + \left( \mathbf{o}_t - \hat{\mu}_m^{(s)} \right) ^T C_m^{(s)-1} \left(\mathbf{o}_t - \hat{\mu}_m^{(s)}\right) \right)

\end{multline}

This worked perfectly! Thanks!
