WebMar 22, 2024 · The math book i'm using states that the cross product for two vectors is defined over R 3: u = ( a, b, c) v = ( d, e, f) is: u × v = i ^ j ^ k ^ a b c d e f and the … 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 ...
