WebDot Product Properties of Vector: Property 1: Dot product of two vectors is commutative i.e. a.b = b.a = ab cos θ. Property 2: If a.b = 0 then it can be clearly seen that either b or a is zero or cos θ = 0. ⇒ θ = π 2. It suggests … Web23 set 2024 · $$\vec{A}=A_{x}\hat{i}+A_{y}\hat{j}+A_{z}\hat{k} $$ Because the dot product is the product of the parts of each vector that are parallel, the dot product of 2 unit vectors that are in the same ...
