"WebThese are the magnitudes of \vec {a} a and \vec {b} b, so the dot product takes into account how long vectors are. The final factor is \cos (\theta) cos(θ), where \theta θ is the angle between \vec {a} a and \vec {b} b. This tells us the dot product has to do with direction. Specifically, when \theta = 0 θ = 0, the two vectors point in ... " - Does order matter in cross product
