WebThe determinant of an orthogonal matrix is +1 or -1. Let us prove the same here. Consider an orthogonal matrix A. Then by the definition: AA T = I Taking determinants on both sides, det (AA T) = det (I) We know that the determinant of an identity matrix is 1. Also, for any two matrices A and B, det (AB) = det A · det B. So det (A) · det (A T) = 1 WebWe interpret the matrix as a list of 3 column vectors, each of which is 2-dimensional. The matrix is sending <1, 0, 0> to the left vector, <0, 1, 0> to the middle vector, and <0, 0, 1> to the right vector. Because they're being mapped to 2D vectors, the range of the transformation is ℝ². WebFeb 9, 2024 · Here W W is always zero, so these functions are always dependent.
