What is the variable in the Plateau curve

  1. Jul 19, 2011 #1
    When m=2n,

    [tex]x=a(1+2\cos(2nt))[/tex]
    [tex]y=2a\sin(2nt)[/tex]

    where

    a is a constant.

    The graph is a circle. Now, what is the variable with respect to which the functions x and y are calculated? Is it n or t? When I tried it on Microsoft Excel, neither created a circle. So I really don't know which one is the variable. Thanks.

    The variable is most likely t. And it gives a circle with center (a,0) and radius 2a.
