## Homework Statement

## Homework Equations

**R**

_{AO}= b(Sinβ

**j**+Cosβ

**k**)

## The Attempt at a Solution

[/B]

The box in red is

**ω**. However I am unsure of where they got the box in blue from? As mentioned above,

**R**

_{AO}= b(Sinβ

**j**+Cosβ

**k**) so not sure where they got the box in blue from? I know of the vector triple product: A x (B x C) = (A•C)B - (A.B)C, but this isn't what they've done?

Thanks
