Ive seen the statement The matrix product of two orthogonal matrices is another orthogonal matrix. on Wolframs website but havent seen any proof online as to why this is true. By orthogonal m In mathematics Vector multiplication refers to one of several techniques for the multiplication of two (or more) vectors with themselves. It may concern any of the following articles Dot product also known as the scalar product an operation that takes two vectors and returns a scalar quanvectory. The dot product of two vectors can be defined as the product of the magnitudes of the two Orthogonal Two non-zero vectors a and b are orthogonal if and only if a b 0. No cancellation Unlike multiplication of ordinary numbers where if ab ac then b always equals c unless a is zero the dot product does not obey the cancellation law

Multiplication of Vectors. Vector multiplications are of two types. One in which we obtain a scalar quanvectory and the other in which we obtain a vector quanvectory on multiplication. The first one is called Dot Product and the other is called Cross Product. (I) Scalar product cos where is the angle between the two vectors when placed tail Also multiplication of two vectors by A also preserves the angle between the two vectors which is characterized by the dot product of the vectors (since the dot product of two unit vectors is the cosine of this angle) as can be seen from Note too that A represents a rotation if det A 1 and a reflection if det A -1. Multiplication of two vectors which produces a scalar is called the scalar product or dot product. a . b scalar. The second type of multiplication which produces a third vector is called Vectors - What Are They gives an introduction to the subject. There are two useful definitions of multiplication of vectors in one the product is a scalar and in the other the product is a vector. There is no operation of division of vectors. In some school syllabuses you will meet scalar products but not vector products but we discuss both
