Question

Three other polar coordinates of:
(3, pi/2)

directrix · Answer

(-3, 3π /2 ) and ( 3, 5π /2 ) and ( -3, 7π /2)

anonymous · Answer

I think I understand this now. Would (-3,-pi/2) also be a coordinate?

directrix · Answer

Yes.

directrix · Answer

Quetion: What are the c(o,o)rdinates of the pole?

anonymous · Answer

Thanks for the help, I have to do a ton of problems involving these and I wanted to make sure I was doing this right. :)

anonymous · Answer

(0,0) right?

directrix · Answer

Yes, but could it more aptly be written as (0,theta) ? I will have to think about that. If the radius is 0, the angle is going nowhere regarding of size. Agree?

directrix · Answer

In polar coordinates the origin is often called the pole. Because we aren’t actually moving away from the origin/pole we know that r = 0 . However, we can still rotate around the system by any angle we want and so the coordinates of the origin/pole are (0.theta). http://tutorial.math.lamar.edu/Classes/CalcII/PolarCoordinates.aspx

Ah, that makes sense. And that website looks like a great resource, thanks!
