    how far from the pole (aka the origin) is that red point?

    so that is the r value

    theta = 5pi/3 is the angle

    (r,theta) = (2.5, 5pi/3)

    so if I needed another angle, would I add 2pi?

    or subtract 2pi

    or you can say (r,theta) = (-2.5, 2pi/3)

    start facing the 2pi/3 direction then walk backwards 2.5 units

    saying 11pi/3 is acceptable as well right?

    yeah (2.5, 5pi/3) (2.5, 11pi/3) (-2.5, 2pi/3) are all the same point

    For the second one could I put (3, 3pi/2) and (3, 7 pi/2)

    r = 4 it looks like it but for some reason they didn't label the scale

    my bad, I meant 4. Thanks for the help!

    (4, 3pi/2) (4, 7pi/2) (-4,pi/2) are 3 of infinitely many ways to label that point
