WebSo this is just going to be a scalar right there. So in the dot product you multiply two vectors and you end up with a scalar value. Let me show you a couple of examples just in case this was a little bit too abstract. So let's say that we take the dot product of the vector 2, 5 and we're going to dot that with the vector 7, 1. Web4 de abr. de 2012 · However, in the case of dot products, the dot product of two vectors a and b is a·b·cos(θ). This means the dot product is the projection of a over b times a. So we divide it by a to normalize to find the exact length of the projection which is b·cos(θ). Hope it's clear.
