Lecture notes and missing lecture video

Hi all,

• As promised I've created a folder in our git repo we're I'll upload my lecture notes. Note that these are just my personal notes for the blackboard lectures, so they may not be very tidy and may contain small reminders to myself that aren't relevant for you. But it can be useful in case you need to double-check something in your own notes.
• Unfortunately, something went wrong with the recording from the second lecture on Friday. However, in that lecture I followed my lecture notes very closely, so if you couldn't attend the lecture you should get a sufficient summary by reading these lecture notes. I discussed initial value problems in general, and the methods Forward Euler, Predictor-Corrector and Runge-Kutta 4, which are all described in Chapter 8 of the main course notes.
