Answer 1

Answer:

Step-by-step explanation:

1.

To convert degreee into radian the multiplying factor is pi/180

Therefore 120*pi/180=2pi/3 radian

2. The coordinate for the circle is rcos thetha,rsin theta

The coordinate of b is 1*cos120,1*sin120....

3. In the complex form the no. Is written as |z|(cos@ +i sin@)

In respect to that |z|= distance between origin and the pt. Which is 2 unit ...

Therefore in complex form z=2(cos120+isin120)

Hope u calculate the given data .. ty
