2. Use the equation Ym(0, $) = (-1 )m (21 + 1) (1 - m )! imo pm (cos !) 4TT (1 + |ml)! to construct Y3 (0, ) and Y!(0, 4). You make look up the definition of P2, but you will have to use the definitions of PM and Pi given in class to determine P. Check that Y?(0, 4) and Y(0, 4) are valid solutions to the Angular equation
