In Preparation

The information below is preliminary and cannot be trusted! (v)

• Reread sections 1.6, 1.7, and 2.1 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. Remember that your prof. thinks that section 1.7 is useless fun. Also, preread the rest of chapter 2, just to get a feel for the future.

• Solve problems 17, 18, 20, 23, 25, 26, 28 and 29a on pages 56-57 and problems 1, 2, 5, 13, 17 and 18 on pages 74-76, but submit only your solutions of the underlined problems. This assignment is due at the tutorials on Thursday October 29.

• Just for fun. Decide if the vectors ${\begin{pmatrix}8\\-3\end{pmatrix}}$ and ${\begin{pmatrix}5\\-2\end{pmatrix}}$ are linearly dependent.

How Can This Be?

Two congruent triangles are assembled using congruent pieces, yet one is bigger than the other
