Question

Given u=(2,5) v=(-2,1), how do you find |u-v|?

Answer 1

Subtract the x of component of v from the x component of u, do the same for the y components, then compute the magnitude of the resulting vector.

Explanation:

`u - v = (2 - -2, 5 - 1)`

`u - v = (4, 4)`

`|u - v| = sqrt(4^2 + 4^2)`

`|u - v| = sqrt(32)`
