For a two dimensional complex vector i = (a b)', where a, b are complex numbers, square of the norm of the vector i is || ||²= |a|2 + |b|². c) Show that R? - 2 cos 0R + I = 0. This must be as dictated by Cayley-Hamilton theorem which we will prove in question 2. d) Find the matrix P that diagonalizes R. That means find P such that eio p-'RP = ( e e) Show that the determinant and the trace are similarity transformation invariant. That means show that: tr (P¯'RP) = tr R, and det (P-RP) = det R
