# Core 4 vectors question (self teaching) ? watch

1. With respect to the origin...

The position vectors are:

L( 4i + 7j + 7k)

M (i+ 3j+ 2k)

N(2i + 4j +6k) Find vectors M to L and M to N

The mark scheme seems to imply that ML is 3i + 4j + 5k

and MN is (1i+ 1j+ 4k)

But I'm not sure how you would obtain these answers?

...

So direction vector of M to L is the position vector L minus the position vector M.

So direction vector of M to L is the position vector L minus the position vector M.
Thank you
