so what is ?
I don't mind how many sites you post on
Geometry help - The Student Room
but it would avoid me wasting my time if you listed them.
Can someone please help me answer this? Can you upload the solutions to this past exam paper question please. I believe AB would essentially be u-w. So that is where i've started but still a bit puzzled here so solutions would be appreciated.
Math Forum Discussions <--- no one has answered here
ok so with part a) i just need to do the dot product then? I don't quite get how I'm to do the dot product on that :/
So once I have the dot product of w&u, do i need to find the dot product of w&v from BC?
