for recording of lecture 14 there is something like a second screen showing how things
are placed which really help me understand the circumstance. But for following lectures
I know the lecturer is showing example while he was recording this lecture, however
there isn't something like a second screen. I'm just wondering is it not recorded or I
didn't turn it on? Thanks.
There is no second screen for the other lectures unfortunately. Only Lecture 14 had the
projector video available. In other lectures, the lecturer is actually mainly referring to
lecture theatre equipment (e.g. desk). No specialised equipment was used there, so the
projector was not used.
