Answer 1

\[\left( -3,-3\sqrt{3} \right)\]

Answer 2

can you find r here?

Answer 3

\(\large r=\sqrt{x^2+y^2} \)

Answer 4

that helps, how would I find theta? since polar is (r,theta)

Answer 5

ok... according to the point that is given, what quadrant is it in?

Answer 6

3

Answer 7

so find a theta that satisfies that?

Answer 8

yes..
use \(\large \theta = arctan \frac{y}{x} \)

Answer 9

can you show me how you got that arctan equation I know its used to find the inverse of tan but can you show me a step before that?
