TRIGONOMETRY

3. The rectangular coordinates of a point are given. Find the polar coordinates of each point.

b. (0,3)

I figured out a, but I canNOT figure out b. Can someone please explain? :)I need to know how to do this for my final next week.

  • TRIGONOMETRY -

    as usual,
    r^2 = x^2+y^2
    r%2 = 9
    r=3

    y/r = sinθ
    3/3 = sinθ
    θ = π/2

    so, we get (3,π/2)

    y/r!! That makes much more sense! Someone else had told me y/x, so that's why it didn't work. Thanks!
