The real part and imaginary part of z are -6 and 6sqrt(3). Which option gives the correct polar form?
A
r = 144; theta = 2pi/3; polar form = 144(cos(2pi/3) + i sin(2pi/3))
B
r = 12; theta = 2pi/3; polar form = 12(cos(2pi/3) + i sin(2pi/3))
C
r = 12; theta = pi/3; polar form = 12(cos(pi/3) + i sin(pi/3))
D
r = 11; theta = 4pi/3; polar form = 11(cos(4pi/3) + i sin(4pi/3))
