    Carthesian equation of Talbot's curve

    Hi!

    I ask for the carthesian equation of Talbot's curve.

    I know only its paramethrical equations

    x=(1-a(sint)^2)cost
    y=(1-a-a(cost^2)sint

    Help me, please|

    Are you saying that x involves sin^2(t) but that y involves sin(t^2)?

    Pardon!
    The correct equations are

    x=(1-a(sint)^2)cost
    y=(1-a-a(cost)^2)sint
