Parametric to Cartesian

  1. Oct 12, 2011 #1
    Can anyone tell me how to convert this parametric equation to cartesian (x,y)?

    r(t)=<2.5+2cos(4t),2.1+1.23sin(4t)>

    I've tried so many ways and they're incorrect.

    Try isolating the cosine and the sine terms and using sin^2(x)+cos^2(x)=1..ex. sin(4t)=(y-.1)/1.23
