Corrected typos in the Fourier/PDE handout:
 In the definition of even function on the first page, there had been a sign missing. Even means f(x)=f(x).
 In the EXAMPLE block after PARSEVAL, the coefficient b_{k} had been called a_{k} before.
 In the block SOLVING THE WAVE EQUATION WITH RFOURIER THEORY, there had been an "n" missing in cos(n c t)

Below are summary handouts to lecture topics. These notes
have been evolved since a few years. They are quite densely written and do not replace
the book of course. If you find typos, please email them or talk to me about it. Errata
found after the notes being distributed are acknowledged to the right. The files found here
are already corrected.
