## Homework Statement

if v x w = <5,5,-2>

(v cross w)

and

v * w = 6

(v dot w)

then what is the tan(θ) between the two vectors v and w?

## The Attempt at a Solution

well I was thinking v x w = |v||w|sinθ

as well as v dot w (v*w) = |v|w|cosθ

divide one equation by the other and the absolute values on the right cancel out,

but then you get a vector divided by a number on the left side equals tanθ

is this how you do this problem?
