\documentclass{article}
\usepackage{amsmath}

\begin{document}

\begin{gather*}
   \frac {a_0}{2} + \sum_{n=1}^{\infty} a_n \cos nx
   + \sum_{n=1}^{\infty} b_n \cos nx \\
   \begin{aligned}
   \text{where}\quad a_n &= \frac {1}{\pi} \int_{-\infty}^{\infty}
               f(x) \cos nx dx \\
    b_n &= \frac {1}{\pi} \int_{-\infty}^{\infty}
               f(x) \sin nx dx
   \end{aligned}
\end{gather*}

or

\begin{equation*}
   \frac {a_0}{2} + \sum_{n=1}^{\infty} a_n \cos nx
   + \sum_{n=1}^{\infty} b_n \cos nx
\end{equation*}
\begin{align*}
   \text{where}\quad a_n &= \frac {1}{\pi} \int_{-\infty}^{\infty}
               f(x) \cos nx dx \\
    b_n &= \frac {1}{\pi} \int_{-\infty}^{\infty}
               f(x) \sin nx dx
\end{align*}
\end{document}
