Question

convert the following complex number to polar (trigonometric) form.

4+3i

Please don't just give me the answer, I would like to know how to get the answer

Answer 1

wanna guess whats the radius

Answer 2

what does it have to do with radius?

Answer 3

polar coordinates need a radius

Answer 4

rsintheta, rcostheta

Answer 5

imagine its plotted real vs imaginary

Answer 6

I havent learn any of these. In my textbook, it tells me:

z=a+bi
z=r(cos # + isin #)

where z = |v| = root(a^2 + b^2) and tan # = b/a

Answer 7

r is the radius here

Answer 8

r can be obtained by taking root of (a^2+b^)

Answer 9

so it will be 5 in your case

Answer 10

oh I even wrote it haha

Answer 11

JOKES

Answer 12

u hacked ur self =)

Answer 13

but how can i find the sin# and cos#

Answer 14

so getting theta should be a piece of cake too

Answer 15

tan theta= b/a
so its tan theta=3/4
theta=36.9 deg

Answer 16

cmon man gr1 math u got this

Answer 17

=P

Answer 18

sorry i dont mean to be condescending do you still have a question??

Answer 19

dw if u didnt get it ill be happy to explain

Answer 20

(i realy wont be)

Answer 21

I think i got it

Answer 22

kk cool

Answer 23

i even wrote it

Answer 24

letme just confirm with you

Answer 25

z = a + bi
tan = b/a
y question is 4+3i
so tan = 3/4

Answer 26

yes

Answer 27

use ur calculator now and find the angle tan^-1

Answer 28

arc tan 3/4 = 36.9

Answer 29

yes

Answer 30

so would the final answer be 36.9?

Answer 31

r sin theta should be 4
r cos theta should be 3
so by now you should realized that teacher hacked u

Answer 32

well i dont know how you wanna leave it

Answer 33

the question is just "Convert the following complex numbers to pola r (trigonometric) form.

Answer 34

(4,3) or 5 sin(36), 5cos(36) or
5 radius, theta=36
are all valid ways of displaying the answer

Answer 35

the thing is, there are like 5 of these questions and this will be on the exam tomorrow lol so it's confusing on which answer to put tomorrow

Answer 36

your teacher will accept the first one for sure
if there is some discrepancy you can ask teacher before test what format she wants it in

Answer 37

this is what I'm assuming
she wants it in form z=r(cos# + isin#)
since that's what the textbook states as the polar form

Answer 38

what do u think?

Answer 39

yeah but if you simplify it, it just comes down to 4,3 =P

Answer 40

but yeah do what the textbook tells u to

Answer 41

maybe it's just solve for z using that form?

Answer 42

lol go study something else dont over think it good night get a good sleep

Answer 43

nop I GOT IT! i read the next page of my textbook and it's basically just writing it as z=r(cos#+isin#).

Answer 44

while filling in each of the things (z, r, #)
