Multiply & divide complex numbers in polar form

w1=22[cos(31π16)+isin(31π16)]w_1=22[\cos(\dfrac{31\pi}{16})+i\sin(\dfrac{31\pi}{16})]
w2=2[cos(15π8)+isin(15π8)]w_2=2[\cos(\dfrac{15\pi}{8})+i\sin(\dfrac{15\pi}{8})]
Express the quotient, w1w2\dfrac{w_1}{w_2}, in polar form.
The angle should be given in radians.
w1w2=\dfrac{w_1}{w_2}=
