  • Read sections 2.1 through 2.3 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 sections 2.4 and 2.5, just to get a feel for the future.
  • Solve problems 20, 21, 24, 25, 26, and 27 on pages 76-77 and problems 1, 5a, 5b, 5c-g, 9, 15 and 16 on pages 84-86, but submit only your solutions of the underlined problems. This assignment is due at the tutorials on Thursday November 5.

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 4\times 4 (!) matrix multiplications in hardware. (The full explanation is very involved; perhaps you should just aim to get a taste of it).

A famed creature that owes its mobility to 4x4 matrices.
