Dot Product of Two Vectors: Definition, Formula & Properties

WebApr 5, 2024 · The scalar product of two vectors is maximum when the vectors are parallel and in the same direction. If the vectors are antiparallel or in the opposite direction, then the scalar product is minimum. The self dot product is defined as = A.A. In this product, the angle between the vectors is equal to zero degrees. In mathematics, the dot product or scalar product is an algebraic operation that takes two equal-length sequences of numbers (usually coordinate vectors), and returns a single number. In Euclidean geometry, the dot product of the Cartesian coordinates of two vectors is widely used. It is often called the inner product (or rarely projection product) of Euclidean space, even though it is not the only inner product that can be defined on Euclidean space (see Inner product space for m… WebSep 15, 2024 · You want the "cost" to represent how far the dot product x.y is from 1.
