WebSep 17, 2024 · The dot product of a vector with itself is an important special case: (x1 x2 ⋮ xn) ⋅ (x1 x2 ⋮ xn) = x2 1 + x2 2 + ⋯ + x2 n. Therefore, for any vector x, we have: x ⋅ x ≥ 0. x ⋅ x = 0 x = 0. This leads to a good definition of length. Fact 6.1.1. The length of a … WebThe way i see it, dot product is a way to define to what extent the two vectors are co-linear. If a and b are orthogonal, you see zero co-linearity. If a and b are 100% co-linear (one is a scaled version of the other), then dot product takes the "Max" value - product of two lengths.
