Determinant of a rotation matrix is equal to

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. Web(4)The 2 £2 rotation matrices Rµ are orthogonal. Recall: Rµ = • cosµ ¡sinµ sinµ cosµ ‚: (Rµ rotates vectors by µ radians, counterclockwise.) (5)The determinant of an orthogonal matrix is equal to 1 or -1. The reason is that, since det(A) = det(AT) for any A, and the determinant of the product is the product of the determinants, we ...
