I am asking for the table for the polar equation -6t

- tkhunny

There is no such thing as "the table". This explains why you cannot find it. Can you provide more information? Is there a specific problem you are working on?

you want to make a table of cartesian coordinates for the polar function \(r(t)=-6t\) ?

- anonymous

@richyw yes

- tkhunny

Notice richyw's use of the phrase "a table". You can make a table on any values you like. This is why "the table" doesn't exist.

- anonymous

Okay. So I am just basically looking for the coordinates of this equation

- richyw

you could make a table of the polar coordinates. so for whatever angle t, you would have whatever radius r. or you could convert these coordinates to cartesian values, which would have x and y values being compared.

- richyw

either way all you are doing is solving this equation for a few values.

- anonymous

No I have polar graph paper and all i need is like the points.

- richyw

ok I see. so then you just directly solve this. choose whatever values of t that you want and then you will get the r value directly from the equation

- anonymous

Can you give me an example? If you don't mind

- richyw

alright well the first point I would do would be at an angle of 0. so\[r(0)=-6(0)=0\] so you know that point will have angle 0 radius 0 (the origin)

- richyw

how many points do you want?

- anonymous

I am going by 30 degrees so until 360

- richyw

are you sure this is in degrees? usually I would assume radians unless it specified.

- anonymous

well radians will be find also

- richyw

not that is makes a difference for the shape though

- anonymous

I understand but I am just trying to graph it

- richyw

ok well then go 30 degrees more (\(\pi/3\) radians)
plug it in \(r(\pi/3)=-6(\pi/3)\)
so \(r=-2\pi\)

- richyw

then plug in \(2\pi/3\) etc until you reach \(2\pi\)

- sirm3d

uhm, 30 degrees is \(\pi /6\)

- richyw

haha oops yup

- anonymous

Your fine you did 60 degrees

- richyw

yup do what I said but every \(\pi/6\)

- richyw

I make that mistake so often...

- anonymous

It's fine we can't remember everything

- richyw

what I would do if I was you is calculate \(2\pi\) first and then it will give you an idea of the scale you need to use for the graph. because it's going to be a spiral shaped thing

Yes I have a art math project I already drew my flower

- anonymous

Hey can you convert that to radians because it will make my day much easier

- richyw

that's already in radians

- anonymous

it is

- richyw

yes if it was in degrees you would have much larger values of r!

- anonymous

yes that's true

- richyw

I suppose if you wanted to see the radius scale in terms of fractions of pi I could open up octave. but you are gonna need to make the table of values anyways if that's what's required...

- anonymous

it is

- sirm3d

here's a graph of the polar equation \(r(t) = 6t\) in the interval \(0 \leq t \leq 2\pi\)
