WebSep 17, 2024 · Definition 4.7.1: Dot Product. Let →u, →v be two vectors in Rn. Then we define the dot product →u ∙ →v as. The dot product →u ∙ →v is sometimes denoted as (→u, →v) where a comma replaces ∙. It can also be written as →u, →v . If we write the … WebThis tells us the dot product has to do with direction. Specifically, when \theta = 0 θ = 0, the two vectors point in exactly the same direction. Not accounting for vector magnitudes, this is when the dot product is at its largest, because \cos (0) = 1 cos(0) = 1. In general, the more two vectors point in the same direction, the bigger the dot ...
