Thus if $g(\nu)$ is known, all thermodynamic properties of the crystal can be
calculated. The specific heat formula is given to compare the Einstein, Debye,
and phonon methods of looking at crystals,
\begin{equation*}
C_v = k \int_{0}^{\inft}{\frac{(h\nu /kT)^2 e^{-h\nu/kT} g(\nu) \d{\nu}{(1 -
e^{-h\nu/kT})^2}}.

defines how quickly the phase changes. By adding another wave in direction $-k$,
we can form a standing wave,

The bounds on the integral are from the fact that $\omega(k) = \omega(|k|)$.
Using chain rule we can eliminate $k$,
\begin{align*}
\d{k} &= \frac{\d{k}}{\d{\omega}} \d{\omega} = \frac{\d}{\d{\omega} {\left[
\frac{2}{a}
\sin^{-1}{\left(\frac{\omega}{\omega_{max}}\right)}\right]}\d{\omega}\\

&= \frac{2 \d{\omega}}{a(\omega^2_{max} - \omega^2 )^{1 /2}}.
\end{align*}
This can be used to rewrite the above integral in terms of $\omega$ with limits
