Question

Convert the equation to polar form.

Y=2

Answer 1

rsin(theta)=2

Answer 2

what's r and theta

Answer 3

r is the the directed distance from the origin and theta is angle starting from the initial ray

Answer 4

how do i find the direction and the theta?

Answer 5

plug in values for thetha to see what r would be for each thetha

Answer 6

just like you would do to f(x)=2 plug in values for x to see what y would be

Answer 7

i'm so confused...

Answer 8

which we know is a horizontal line because y doesn't change no matter x we put in

Answer 9

yes

Answer 10

how are you confused? just plug in values for thetha like you would x

Answer 11

so f(2)=2

Answer 12

something like that

Answer 13

yes

Answer 14

the answer would than be 4?

Answer 15

or do i divide?

Answer 16

? i don't understand what you are doing?
i thought you were just showing an example of plugging in somthing for x

Answer 17

hey loco i'm scanning something for you

Answer 18

loco polar coordinates should be easy.
why are you making it so difficult
lol

Answer 19

the most inner circle on that graph is radius 1
the second most inner circle is radius 2

Answer 20

and so on

Answer 21

i tend to make things more difficult than they already are.

Answer 22

Thanks so much for your help :)

Answer 23

do you understand what I did

Answer 24

somewhat, but i'll get it i got rest of the night :P

Answer 25

are you having trouble graphing or plotting polar points?

Answer 26

both

Answer 27

do you know your ti83 if you have one can graph polar equations

Answer 28

we can't use calculators in any math classes at my college

Answer 29

i'm trying to do it without them

Answer 30

and i don't know how to do it on them because we never learned

Answer 31

neither did i until just now
i was like can this even graph polar equations
and i was like cool

Answer 32

it really helps if you know the unit cirlce
do you know the unit circle
in fact you cant do this without the unit circle

Answer 33

i'm still trying to remember it. i know most of it but mix up some of the numbers sometimes

Answer 34

here is a couple of plotted polar coordinates

Answer 35

thanks :) really helpful
