The assignments (and solutions) are on Ruth’s MA22S3 page and are worth 20% of your grade.

Conor’s notes from 2012 and his 231.II notes might be helpful. Darran also has some excellent notes on Fourier analysis (§§1,2).

I tutored this course before and my teaching page for it has a couple of nice proofs. (The course used to be in x and k for position and momentum, but now we use t and ω.)

Here’s a derivation of the Fourier series from a Hilbert space perspective, which explains why there is a factor of a half in the a₀ term.

I was asked to upload my solutions to the tutorials, so here they are.

Colm’s course page (with notes) is here. I teach the tutorial with Fritz. It’ll be worth 20% of your grade at the end.

The assignments are written by Diana, Robbie, Mairéad and myself and are published weekly here. The official course descriptor has information about continuous assessment, etc.

Rupert Levene’s notes from four years ago are here, along with tutorials and solutions to past exam papers.

See the course webpage for details, tutorials and notes.

If you’re struggling, I’m told that Khan Academy can be quite helpful.
