Eliminate the parameter and write the corresponding rectangular equation whose graph represents the curve.

x = sqrt t
y = 1 - t

  • Math -

    from first:
    x = √t
    so x^2 = t

    from the second
    t = 1-y

    so x^2 = 1 - y
    or
    y = 1 - x^2 , a parabola

  • Math -

    A polygon with 4 sides no two of wich need to be the same size
