The angle between two vectors can be found in terms of their:
AVector negation
BPosition vector
CVector product
DVector addition
Answer & Solution
Correct answer: C. Vector product
1. The magnitude of the cross product involves the sine of the angle.
2. That relation can be turned round.
3. So the angle may be given in terms of the vector product.
