**Readings Questions:**

You should read the section before
attempting any reading questions or problems. Remember that you are responsible
for all definitions and examples. **Also remember to keep the answers
to the reading questions on a separate piece of paper; these will be randomly
collected from time to time.**

1) The text uses Theorem
1.7.1 part (2) to prove that **a** x **b**
= **0** when **a**
and **b** are linearly dependent.
Prove this directly using the definition of linearly dependent and the
definition of **a** x **b**.

2) Verify equation (1.7.6).

3) Consider problem
#2 on page 65.

a) Do part a) and then discuss when **a**
x **b** = **b** x **a**.

b) Do part b).

**Problems:**
