Question 278378: Give the polar coordinates: (0, -3).
Answer by nyc_function(2741)   (Show Source):
You can put this solution on YOUR website! We need to convert to the form (r, theta).
(1) Graph the given point on the xy-plane.
(2) From the graph we can see that the radius is the distance from the origin to the point (0, -3). So, the radius is 3.
(3) We ow need to find theta.
If we begin to rotate from the positive measure on the x-axis to the given point (0,-3), we will end our rotation on the y-axis below the x-axis where the value of theta is 270 degrees.
So, (0,-3) can be written as (3, 270) in polar form.
