The dot product of two vectors 𝐀 and 𝐁 is defined as the magnitude of vector 𝐀 times the magnitude of vector 𝐁 times the cos of πœƒ, where πœƒ is the angle formed between vector 𝐀 and vector 𝐁. In the case of these two perpendiculars, vector 𝐀 and vector 𝐁, we know that the angle between the vectors is 90 degrees.Theorem 1.5 (Geometric interpretation of the dot product). If is the angle between the two vectors ~uand ~v, then ~u~v= j~ujj~vjcos : Proof. If either ~uor ~vis the zero vector, then both sides are zero, and we certainly have equality (and we can take to be any angle we please, which is consistent with our convention that the zero vector points inLet a = <-2,5> and b = <-4,10>, then we can write b as b = 2 <-2,5> = 2a. That means a and b are parallel vectors. How to Find Dot Product of Parallel Vectors? In order to find the dot product of two parallel vectors, we just need to find the product of the magnitude.

So we have the equation, Aβ‹… β‹… B = AB cos ΞΈ cos.The dot product of two unit vectors behaves just oppositely: it is zero when the unit vectors are perpendicular and 1 if the unit vectors are parallel. Unit vectors enable two convenient identities: the dot product of two unit vectors yields the cosine (which may be positive or negative) of the angle between the two unit vectors.We would like to be able to make the same statement about the angle between two vectors in any dimension, but we would first have to define what we mean by the angle between two vectors in \(\mathrm{R}^{n}\) for \(n>3 .\) The simplest way to do this is to turn things around and use \((1.2 .12)\) to define the angle.
