Prove that the product of matrix [cos2 0 cos0sin0 (below dis)cos0sin0 sin2 0] & [cos2alpha cosalphasinalpha (below dis)cosalphasinalpha sin2 0] is a null matrix where 0 & alpha diffre by an odd multiple of pie / 2.

Prove that the product of matrix [cos² 0 cos0sin0 (below dis)cos0sin0 sin² 0] & [cos²alpha cosalphasinalpha (below dis)cosalphasinalpha sin² 0] is a null matrix where 0 & alpha diffre by an odd multiple of pie / 2.
