WebDefinition of Orthogonal Matrix The square matrix P is orthogonal when it is invertible and P − 1 = P T. 1. Show that the matrix P defined previously is not orthogonal. 2. Show that for any real number θ, the matrix [cos θ sin θ − sin θ cos θ ] is orthogonal. 3. Show that a matrix is orthogonal if and only if its columns are pairwise ... WebOrthogonal Projection. In this subsection, we change perspective and think of the orthogonal projection x W as a function of x . This function turns out to be a linear transformation with many nice properties, and is a good example of a linear transformation which is not originally defined as a matrix transformation.
