The rectangular coordinates of a point are given (0,-6). Find polar coordinates of the point such that r greater than 0

Question

and 0 less than or equals
theta less than 2pi.
how to solve this damon please help me

Answer 1

r = 6
straight down = (3/4)(2 pi)
= 3 pi/2 = 1.5 pi

Answer 2

Hey, sketch this stuff on a rough graph.

Answer 3

didnt get it
how r is 6 and from where does 3/4 come
if suppose that no are 3,-3root3 then?

Answer 4

x = 0
y = -6

that is 6 units directly below the origin
so
r = 6 = sqrt(0^2+6^2)

you are three quarters of the way around to two pi

Answer 5

you could say that r = -6 and theta = pi/2 but that is no good, r must be +

Answer 6

got it thank you

Answer 7

whew, good !
