## anonymous one year ago MEDAL AWARDED: Find the rectangular coordinates of the point with the polar coordinates (1, 1 divided by 2 pi). Would the answer be (1, 0) ?

1. anonymous

And Determine two pairs of polar coordinates for the point (2, -2) with 0° ≤ θ < 360°.

2. Ac3

for the polar coordinates is this what you mean (1,pi/2)?

3. anonymous

no, I meant (1, 1/2pi)

4. anonymous

$(1, \frac{ 1 }{ 2 }\pi)$

5. Ac3

that's the same thing

6. anonymous

Yes, just wanted to make it clearer.

7. Ac3

ok in that case the rectangular coordinates are (0,1)

8. anonymous

Oh ok, how?

Oh I got it now. (:

14. anonymous

I will. Thank you.

15. Ac3

That's an easy method there to memorize it. No problem

16. anonymous

Could you see if you could do 1 more?

17. anonymous

I got an answer, just wanted to make sure it was right.

Find all polar coordinates of point P = (2, 14°). I got (2, 14degrees + 360n) and (-2, 14degrees + (2n+1)180degrees)
