Does anyone now the table for the polar equation -6t(t is degree or radians)? No any helpful websites to help me get the table for this
I am asking for the table for the polar equation -6t
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 \(r(t)=-6t\) ?
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.
Okay. So I am just basically looking for the coordinates of this equation
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.
either way all you are doing is solving this equation for a few values.
No I have polar graph paper and all i need is like the points.
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
Can you give me an example? If you don't mind
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)
how many points do you want?
I am going by 30 degrees so until 360
are you sure this is in degrees? usually I would assume radians unless it specified.
well radians will be find also
not that is makes a difference for the shape though
I understand but I am just trying to graph it
ok well then go 30 degrees more (\(\pi/3\) radians) plug it in \(r(\pi/3)=-6(\pi/3)\) so \(r=-2\pi\)
then plug in \(2\pi/3\) etc until you reach \(2\pi\)
uhm, 30 degrees is \(\pi /6\)
Your fine you did 60 degrees
yup do what I said but every \(\pi/6\)
I make that mistake so often...
It's fine we can't remember everything
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
Hey can you convert that to radians because it will make my day much easier
that's already in radians
yes if it was in degrees you would have much larger values of r!
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...
here's a graph of the polar equation \(r(t) = 6t\) in the interval \(0 \leq t \leq 2\pi\)
