PLEASE HELP!!! MEDAL WILL BE REWARDED!
Determine two pairs of polar coordinates for the point (2, -2) with 0° ≤ θ < 360°

I got to ((radical225+pi^2)/3,0) but i cant figure out the rest of the problem!

Answer 1

\[\sqrt{225 + \pi^2}/3, 0\]

Answer 2

you need \(r\) and \(\theta\)

Answer 3

\(r=\sqrt{2^2+2^2}=\sqrt{8}=2\sqrt{2}\)

Answer 4

Would it be (2 , (radical2), 225°), (-2 ,(radical2), 45°)

Answer 5

now you have an infinite number of choices for \(\theta\)

Answer 6

you can use \(\theta=-45\) or \(\theta=315\) or whatever

Answer 7

or you can use what you said,
\[(-2\sqrt{2},45)\]

Answer 8

Okay, but that order would be correct? not the other way around? @satellite73

Answer 9

yes, it is \((r, \theta)\)

Answer 10

Okay thanks again :)
