Web24 de mar. de 2024 · The dot product can be defined for two vectors X and Y by X·Y= X Y costheta, (1) where theta is the angle between the vectors and X is the norm. It follows immediately that X·Y=0 if X is perpendicular to Y. The dot product therefore has the geometric interpretation as the length of the projection of X onto the unit vector Y^^ when … WebIn mathematics, the simplest form of the parallelogram law (also called the parallelogram identity) belongs to elementary geometry. It states that the sum of the squares of the lengths of the four sides of a parallelogram equals the sum of the squares of the lengths of the two diagonals. We use these notations for the sides: AB, BC, CD, DA.
