Web6. To define vector division as the scalar result of one vector "divided" by another, where the scalar times the denominator vector would then give us the numerator vector, we can write the following: u → = w v → u → ⋅ v → = w v → ⋅ v → ∴ w = u → ⋅ v → v 2. The math for a scalar quotient works. That is one way to divide ... WebThe vector form is used to represent a line or a plane in a three-dimensional space.
