Question

Select correct polar form of given z = -2 *

1) z = √2( cos π + i sin π )

2) z = 2( cos 60⁰ + i sin 60⁰)

3) z = 2( cos π + i sin π )

4) z = 2 ( cos 90⁰ + i sin 90⁰)​

Answer 1

Answer:

2.) option is correct

Step-by-step explanation:

because mode is under root (-2)²+0²=2

and angle is pi
