Samples of parametric equations

  1. Sep 5, 2007 #1
    I need samples of parametric equations:
    x=Fx(t);
    y=Fy(t);

    the samples must be useful or famous in math, physics or engineer, not be created randomly meaningless.

    one that I know is to describle ellipse:
    x=A*cos(t);
    y=B*sin(t);

    I need 2 or more good samples for my report.

    thanks.

    found so far:

    Cycloid
    Epicycloid
    Hypocycloid
    Hypotrochoid
    Spirograph

    A cycloid is a good example. Look it up.

    nicktacik,
    thanks.
    by your clue, i found a set of them:

    Cycloid
    Epicycloid
    Hypocycloid
    Hypotrochoid

    I add them in my post and will use them soon.

    Any other interesting locus?
