Question

Convert the following complex number into its polar representation: -4i

Answer 1

what will the radius be?

Answer 2

think about the point (0,4) what angle goes to this point?

Answer 3

not sure :/

Answer 4

the complex standard form is "a+bi"

you have pretty much as zzr0ck3r already suggested
0-4i
so
0 -4i
a b

(a, b) elements

Answer 5

a

Answer 6

b

Answer 7

c

Answer 8

um those are not polar....

Answer 9

d

Answer 10

so you'd want to convert it to the polar form of \(\large r = (cos(\theta) + isin(\theta)\)

Answer 11

these are my answer choices :/

Answer 12

polar = (radius,angle)

Answer 13

so, bear in mind that \(r = a^2 + b^2\)

Answer 14

woops darn

Answer 15

\(r^2 = a^2 + b^2\)

Answer 16

its C?

Answer 17

dunno

Answer 18

so you dont know ?

Answer 19

well, we haven't gotten the value for "r"

Answer 20

how do you do that
