rsin(theta)=2

- anonymous

what's r and theta

- myininaya

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

how do i find the direction and the theta?

- myininaya

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

- myininaya

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

- anonymous

i'm so confused...

- myininaya

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

- anonymous

yes

- myininaya

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

- anonymous

so f(2)=2

- anonymous

something like that

- myininaya

yes

- anonymous

the answer would than be 4?

- anonymous

or do i divide?

- myininaya

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

- myininaya

hey loco i'm scanning something for you

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

- myininaya

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

- myininaya

and so on

- anonymous

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

- anonymous

Thanks so much for your help :)

- myininaya

do you understand what I did

- anonymous

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

- myininaya

are you having trouble graphing or plotting polar points?

- anonymous

both

- myininaya

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

- anonymous

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

- anonymous

i'm trying to do it without them

- anonymous

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

- myininaya

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

- myininaya

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

- anonymous

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

- myininaya

here is a couple of plotted polar coordinates
