Lecture notes is fun \eqref{test}.

\begin{align}
    E &= mc^2 \label{test} \\\\\
      &= mv^s \nonumber
\end{align}

$\omega = 2 \pi f$

In equation \eqref{eq:sample}, we find the value of an
interesting integral:

\begin{equation}
  \int_0^\infty \frac{x^3}{e^x-1}\,dx = \frac{\pi^4}{15}
  \label{eq:sample}
\end{equation}

\begin{bmatrix}
  a & b \\\\\
  c & c
\end{bmatrix}
