## Homework Statement

If the cross product of vector v cross vector w = 3i + j + 4k, and the dot product of vector v dot vector w = 4, and theta is the angle between vector v and vector w, find tan(theta) and theta.

## Homework Equations

vector c = |v||w| sin(theta) where vector c is the cross product of v and w.

## The Attempt at a Solution

I'm assuming you have to split the cross product back into the two original vectors and then calculate the angle but I'm not sure how to go from cross product to 2 vectors. Please help!
