Convert to a rectangular equation by eliminating the parameter:
x=sin(theta)
y=(cos theta)^2

  • Calculus - , Saturday, April 13, 2013 at 11:37pm

    from y = cos^2 Ø
    y = 1 - sin^2 Ø
    sin^2 Ø = 1-y
    sinØ = √(1-y)

    so sinØ = x and sinØ = √(1-y) , so

    x = √(1-Y)
    or
    x^2 = 1-y
