WebThe angle between two vectors, θ, is defined by the formula: v ⋅ w = ‖v‖2‖w‖2cosθ. The dot product is a measure of how similarly directed the two vectors are. For example, the vectors (1,1) and (2,2) are parallel. If you compute the angle between them using the dot product, you will find that θ = 0. Web24 aug. 2024 · An important observation here is that for perpendicular vectors the dot product is zero.a.b = 0as cos (90) = 0.
