 More complex equations can be written using symbols and commands from math-mode. An example is the Fourier coefficients equations \eqref{eq:a0},\eqref{eq:an} and \eqref{eq:bn}:
-\begin{eqnarray}
-  a_0=\frac{1}{T}\int_0^T f(t)dt  \label{eq:a0}\\
-  a_n=\frac{2}{T}\int_0^T f(t)\cdot \cos{\left(\frac{2\pi nt}{T}\right)}dt  \label{eq:an}\\
