How do you work out the magnitude of two vectors?
2. Re: vectors
You work out the magnitude of a vector by using Pythagoras' theorem

Aha I see, so what would be the magnitude of C
A=(4) B=(2) c=(6)
( -2 ) (3) (5)

Sorry I've not drawn the vectors particularly well :L

5. Re: vectors
if C =

6
5

then |c|^2 = 6^2 + 5^2

what does ^ mean?
Its used for writing powers.

2^2 = 2 squared = 4.
