The definition is as follows. Definition 4.7.1: Dot Product. Let be two vectors in Rn. Then we define the dot product →u ∙ →v as →u ∙ →v = n ∑ k = 1ukvk. The dot product →u ∙ →v is sometimes denoted as (→u, →v) where a comma replaces ∙. It can also be written as →u, →v .This combined dot and cross product is a signed scalar value called the scalar triple product. A positive sign indicates that the moment vector points in the positive \(\hat{\vec{u}}\) direction. and multiplying a scalar projection by a unit vector to find the vector projection, (2.7.10)The dot product is equal to the cosine of the angle between the two input vectors.
