Hi all,
Just to clarify  should equation 9 in the notes for lecture 12 (http://www.math.toronto.edu/courses/apm346h1/20129/L12.html#mjxeqneq9) read
$\lambda_n =  n^2 \pi^2 / l^2$ ?
Cheers,
Ian

Yes, there was an error: correct: $\lambda_n = n^2 \pi^2 / l^2$ and also unnumbered equation above (7) should be
\begin{equation*}
\frac{ T''(t)}{T(t)}=c^2\lambda,\qquad \frac{ X''(x)}{X(x)}={\color{red}{}}\lambda
\end{equation*}
