Answer:
<h2>
6cis120°</h2>
Step-by-step explanation:
The general form of a complex number z = x+iy
If x = rcos
and y = rsin
where r is the modulus of the complex number and
is the argument, z in polar form is represented as:
z = rcos
+ rsin
z = r(cos
+ isin
)
z = rcis
Given the complex number z=−3+3√3i
r = 


since the argument is negative and tan is negative in the 2nd and 4th quadrant,
In the second quadrant, theta = 180- 60 = 120°
On substituting r and theta, the complex number in polar form is expressed as 6cis120°
