Read sections 2.4, 3.1 and 3.2 in our textbook. Remember that reading math isn't like reading a novel! If you read a novel and miss a few details most likely you'll still understand the novel. But if you miss a few details in a math text, often you'll miss everything that follows. So reading math takes reading and rereading and rerereading and a lot of thought about what you've read. Also, preread section 2.5, just to get a feel for the future.

Solve problems 1, 2, 4 and 9 on pages 106-107, problems 1, 2 and 9 on pages 151-152 and problems 1, 2aceg, 2bdf, 7, 19 and 21 on pages 165-168 but submit only your solutions of the underlined problems. This assignment is due at the tutorials on Thursday November 16.

Just for fun. Do a web search for the words "OpenGL" and "matrix" (or "matrices") and find out why graphics accelerators in PCs and game consoles do (!) matrix multiplications in hardware. (The full explanation is very involved; perhaps you should just aim to get a taste of it).
