\begin{theorem}[Fourier coefficients of even and odd functions]
Recall that a function is said to be \emph{even} if \(f(-x) = f(x)\) or \emph{odd} if \(f(-x) = -f(x)\). We can show that if a function is
\begin{itemize}
- \item odd, then \(b_n = 0\) for all \(n\), and
+ \item even, then \(b_n = 0\) for all \(n\), and
\[
a_n = \frac{4}{T}\int\limits_0^{T/2} f(t)\cos(n\omega t)\di{t}
\]
- \item even, then \(a_n = 0\) for all \(n\), and
+ \item odd, then \(a_n = 0\) for all \(n\), and
\[
b_n = \frac{4}{T}\int\limits_0^{T/2} f(t)\sin(n\omega t)\di{t}
\]
