- TL;DR Summary
- I am hoping for advice on how to approach a what I assume to be cross product related problem that I have never encountered before

I am beginning this new general physics course and I have encountered a question involved with what I assume to be cross products, a topic that I have very little experience with. I am not looking for a direct answer to the problem but advice on what steps should be taken in order to learn how to answer the problem. The problem is as follows,

Demonstrate the following relationship: a x (b x c) = (a

Starting from this relationship derive expressions for the following

(a x b)

(a x b)^2

Demonstrate the following relationship: a x (b x c) = (a

**·**c)b - (a**·**b)cStarting from this relationship derive expressions for the following

(a x b)

**·**(c x d)(a x b)^2
