(linear algebra) A scalar product.

(linear algebra) a vector with the size given by the product of two vectors computed as the product of the magnitudes of the vectors and the sine of the angle between their directions, and directed perpendicular to the given two vectors, with positive orientation.

(linear algebra) The product of two vectors computed as the sum of the corresponding elements of the vectors, or, equivalently, as the product of the magnitudes of the vectors and the cosine of the angle between their directions.

(law) The duty upon a party in a legal proceeding to introduce enough evidence relating to an assertion of fact to have the issue be considered by the fact-finder rather than summarily dismissed or decided; part of the burden of proof.

(linear algebra) A vector product.

(cinematography, television) The stages of film (or audio) production happening between the actual filming (or recording) and the completed product.

(set theory) The set of all possible pairs of elements whose components are members of two sets. Notation: X⨯Y=(x,y)|x∈X∧y∈Y.

(arithmetic) The result of multiplying no numbers, conventionally defined to equal one.

A final product, especially one resulting from a series of stages or processes.

(cinematography) The process of preparing the elements involved in a motion picture, theatrical play, or other performance.
