WebIn general, the more two vectors point in the same direction, the bigger the dot product between them will be. When \theta = \dfrac {\pi} {2} θ = 2π, the two vectors are precisely perpendicular to each other. This corresponds to the dot product between them being 0 0, because \cos\left ( \dfrac {\pi} {2} \right) = 0 cos(2π) = 0.
