Convert the equation to polar form.

Y=2

Question

Convert the equation to polar form.

Y=2

myininaya · Answer

rsin(theta)=2

anonymous · Answer

what's r and theta

myininaya · Answer

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

anonymous · Answer

how do i find the direction and the theta?

myininaya · Answer

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

myininaya · Answer

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

anonymous · Answer

i'm so confused...

myininaya · Answer

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

anonymous · Answer

yes

myininaya · Answer

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

anonymous · Answer

so f(2)=2

anonymous · Answer

something like that

myininaya · Answer

yes

anonymous · Answer

the answer would than be 4?

anonymous · Answer

or do i divide?

myininaya · Answer

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

myininaya · Answer

hey loco i'm scanning something for you

myininaya · Answer

attachment

myininaya · Answer

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

myininaya · Answer

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

myininaya · Answer

and so on

anonymous · Answer

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

anonymous · Answer

Thanks so much for your help :)

myininaya · Answer

do you understand what I did

anonymous · Answer

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

myininaya · Answer

are you having trouble graphing or plotting polar points?

anonymous · Answer

both

myininaya · Answer

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

anonymous · Answer

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

anonymous · Answer

i'm trying to do it without them

anonymous · Answer

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

myininaya · Answer

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

myininaya · Answer

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 · Answer

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

myininaya · Answer

here is a couple of plotted polar coordinates

anonymous · Answer

thanks :) really helpful
