Web(h) Why is the recursive formula for the determinant of an n × n matrix A: det(A) = 1 X i (-1) i + j a ij det A ij (13) so difficult for computers to use for large n? ANSWER: Because for an n × n matrix, we must make n! / 2 com-putations of determinants of 2 × 2 matrices. This is an extremely fast growth rate in n. We have seen the existence of several decompositions that apply in any dimension, namely independent planes, sequential angles, and nested dimensions. In all these cases we can either decompose a matrix or construct one. We have also given special attention to 3 × 3 rotation matrices, and these warrant further attention, in both directions (Stuelpnagel 1964). Given the unit quaternion q = w + xi + yj + zk, the equivalent pre-multiplied (to be used with colu…

WebJan 27, 2024 · Using the definition of a determinant you can see that the determinant of a rotation matrix is cos2 (θ)+sin2 (θ) which equals 1. A geometric interpretation would be that the area does not change, this is clear because the matrix is merely rotating the picture and not distorting it in any other way.
