One can identify complex numbers and vector on the plane r 2 as a+ib ≡ (a, b). find the matrix b = [ b11 b12 b21 b22] such that, using this identification, e iϕ(a + ib) ≡ ( b [ a b ])t where t denotes the transpose. now use this to explain geometrically the action of the matrix b on the vector [ a b ] .
