    And Determine two pairs of polar coordinates for the point (2, -2) with 0° ≤ θ < 360°.

    for the polar coordinates is this what you mean (1,pi/2)?

    ok in that case the rectangular coordinates are (0,1)

    and I'm not sure about the other one. Learn your unit circle by the way. https://www.youtube.com/watch?v=cIVpemcoAlY

    Find all polar coordinates of point P = (2, 14°). I got (2, 14degrees + 360n) and (-2, 14degrees + (2n+1)180degrees)
