WebMar 8, 2011 · The wedge product of two vectors in ℝ³ gives the area of parallelogram they enclose & it can be interpreted as a scaled up factor of a basis vector orthogonal to the vectors. So (e₁⋀e₂) is an orthogonal unit vector to v & w & (v₁w₂ - v₂w₁) is a scalar that also gives the area enclosed in v & w. 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 vectors as column or row matrices, it is equal to the matrix product →v→wT.
