WebA vector has magnitude (how long it is) and direction:. Two vectors can be multiplied using the "Cross Product" (also see Dot Product). The Cross Product a × b of two vectors is another vector that is at right angles to … WebThis means the Dot Product of a and b. We can calculate the Dot Product of two vectors this way: a · b = a × b × cos (θ) Where: a is the magnitude (length) of vector a. b is the magnitude (length) of vector b. θ is the angle between a and b. So we multiply the length of a times the length of b, then multiply by the cosine ...
