What follows is a transcription of these notes, which were written by James Keck during a two-part course in "Mathematical Methods",Presumably for physics. taught by Richard Feynman in the fall of 1946 through the spring of 1947.

If Dr. Keck was anything like I was as a note-taker, he probably wrote down most of this in a hurry. I've added my own notes In sidenotes, like this one! pointing out skipped leaps in reasoning and hopefully adding some extra mathematical rigor; fleshed out some of the verbiage so it reads more smoothly; and corrected the occasional mistake.
