Even though it existed with the emergence of the first. person, management concept which is defined as carrying out. the work through people in general, it is thanks to Taylor that. it was called as âscienceâ. Taylor is a pioneering model due. to his initiations for creating the science of production studies.

An orthogonal matrix Q is necessarily invertible (with inverse Qâ1 = QT), unitary (Qâ1 = Qâ) and therefore normal (QâQ = QQâ) in the reals. The determinant of any orthogonal matrix is either +1 or â1. As a linear transformation, an orthogonal matrix preserves the dot product of vectors, and therefore acts as an isometry of Euclidean space, such as a rotation or reflection. In other words, it is a unitary transformation. The set of n Ã n orthogonal matrices forms a group O(n), known as the orthogonal group. The subgroup SO(n) consisting of orthogonal matrices with determinant +1 is called the special orthogonal group, and each of its elements is a special orthogonal matrix.
