12240/Homework Assignment 6

This assignment is due at the tutorials on Thursday November 15. Here and everywhere, neatness counts!! You may be brilliant and you may mean just the right things, but if the teaching assistants will be having hard time deciphering your work they will give up and assume it is wrong.
Task 1. 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.
Task 2. Solve problems 20, 21, 24, 25, 26, and 27 on pages 7677 and problems 1, 5a, 5b, 5cg, 9, 15 and 16 on pages 8486, but submit only your solutions of the underlined problems.
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 quite involved; perhaps you should just aim to get a taste of it).
