WebJun 21, 2024 · Scalar product or dot product of two vectors is an algebraic operation that takes two equal-length sequences of numbers and returns a single number as result. In geometrical terms, scalar products can be found by taking the component of one vector in the direction of the other vector and multiplying it with the magnitude of the other vector.
