Hi,
I tried solving the Euler ODE (3) in the lecture 30 notes, but by plugging in P:=Ï^{m} as usual I obtained Î»=m(m+1) from the characteristic equation not Î»=l(lm+1) as is given in the notes. I was wondering where this l comes from? Also, in equation (5) m=1 is chosen. Why?
Thank you!

Because it was a series of misprints after (30.3 (http://www.math.toronto.edu/courses/apm346h1/20129//L30.html#mjxeqneq3)). Thanks for spotting

Have the lecture 30 notes been altered? The link above is not working for some reason. The notes in the original link on the homepage still have the 'l' and m=1. Thanks!

because it was a wrong linktry again. I think I replaced everywhere $m$ by $l$ in this place ($m$ appears later and runs from $l$ to $l$).
