Question

Unit vectors and are directed east and north, respectively. Calculate the unit vector (in terms of ihat and jhat) in the northeast direction

Answer 1

I+j
The vector is exactly between north and east, so it points to northeast

Answer 2

The not vector will be sqrt2/2i + sqrt2/2j

Answer 3

so that answer is just root 2/2 I + rt 2/2j?

Answer 4

(root(2))/2i + (root(2))/2j
See if you can achieve to that by yourself
