    Give the pairs of polar coordinates for the point (-6,0)


    I understand how to get the polar coordinate,I just don't understand how you would get two coordinates..?
    Thank you!

    One point can have many polar coordinates. I get (6,180) & (6,0). You get the other coordinate by rotating theta 180 degrees.

    Nope, you would get 0. The pair of polar coordinates for (-6,0) are (6,180) & (6,0)
