In conclusion to this section, we want to stress that “dot product” and “cross product” are entirely different mathematical objects that have different meanings. The dot product is a scalar; the cross product is a vector. Later chapters use the terms dot product and scalar product interchangeably.

Parallel Vectors The total of the products of the matching entries of the 2 sequences of numbers is the dot product. It is the sum of the Euclidean orders of magnitude of the two vectors as well as the cosine of the angle between them from a geometric standpoint. When utilising Cartesian coordinates, these equations are equal.
