Answer 2

Because the real part (a) of the complex number is zero, you cannot use

θ

=

tan

−

1

(

b

a

)

; you must know that the angle is either

π

2

or

3

π

2

. Because the sign of the complex part is negative, you must know that this makes the angle the latter,

3

π

2

.

θ

=

3

π

2

You can see that the magnitude is 2.

The polar form is:

2

(

cos

(

3

π

)

+
