That's it. I found the first half OK, but got lost completely by week 10. I'm probably no longer that good at maths, but I like to blame the fact that I was doing 30UOC, and never did the pre-reqs (I had no clue about Fourier representations, for example).http://web.maths.unsw.edu.au/~jagr/mmde.pdf
If that's the entire MATH2130 content it doesn't look too hard.
The notes may need cleaning up.
