HW is to review questions in light of today's class.
I have also as requested uploaded '2 special triangles' (click here) - this is a 1 page file explaining the relationships in triangles with 60, 30 and 90 degrees and 45. 45, 90 degrees. Students should be able to reproduce these from memory.
We have decided to move on to a new topic tomorrow and perhaps have a 2nd Complex Numbers test next Monday 4 Feb.
