In Section 2.6, Example 2, equation (14) it is written:
$$\begin{multline}
\psi(x)=c\int_0^{x/c}q(t')\,dt'+\phi(x)=\\
c\int_0^{x/c}q(t')\,dt'+\frac{1}{2}g(x) +
\frac{1}{2c}\int_0^{x}
h(x')\,dx'.
\qquad \label{eq2.6.14}
\end{multline}$$
But I believe the expression should contain $$\phi(x)$$ not $$\phi(x)$$ as follows from $$\phi(x)\psi(x)=c\int_0^{x/c}q(t')\,dt'$$

Yeah it should be $ \phi(x)$ but in the next line they correctly included x in the g(x) and h(x) functions so I don't think it should change any following equations

Thanks. Corrected
