Homework Statement
"PRQSTU is a regular hexagon of side 2 units. PQ,QR and RS represent vectors a, b andc respectively. Find the value of a.(b + c)
The hexagon is a regular hexagon starting at the far left (ie pointing left) with P then anti clockwise through U at the top left.
Homework Equations
None that I can think of.
The Attempt at a Solution
I really don't know where to start. I've guessed that a (PQ) = -c. But I don't know where to go from there and now I'm really confused.
Any help greatly appreciated.
