## TammyFlow Group Title 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 one year ago one year ago

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

3. tkhunny Group Title

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?

4. richyw Group Title

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

5. TammyFlow Group Title

@richyw yes

6. tkhunny Group Title

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.

7. TammyFlow Group Title

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

8. richyw Group Title

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.

9. richyw Group Title

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

10. TammyFlow Group Title

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

11. richyw Group Title

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

12. TammyFlow Group Title

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

13. richyw Group Title

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)

14. richyw Group Title

how many points do you want?

15. TammyFlow Group Title

I am going by 30 degrees so until 360

16. richyw Group Title

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

17. TammyFlow Group Title

well radians will be find also

18. richyw Group Title

not that is makes a difference for the shape though

19. TammyFlow Group Title

I understand but I am just trying to graph it

20. richyw Group Title

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

21. richyw Group Title

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

22. sirm3d Group Title

uhm, 30 degrees is $$\pi /6$$

23. richyw Group Title

haha oops yup

24. TammyFlow Group Title

Your fine you did 60 degrees

25. richyw Group Title

yup do what I said but every $$\pi/6$$

26. richyw Group Title

I make that mistake so often...

27. TammyFlow Group Title

It's fine we can't remember everything

28. richyw Group Title

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

29. richyw Group Title

30. TammyFlow Group Title

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

31. TammyFlow Group Title

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

32. richyw Group Title

33. TammyFlow Group Title

it is

34. richyw Group Title

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

35. TammyFlow Group Title

yes that's true

36. richyw Group Title

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...

37. TammyFlow Group Title

it is

38. sirm3d Group Title

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

Thanks
