How do you find the parametric equations for the rectangular equation #x^2+y^2-25=0# ? Calculus Parametric Functions Introduction to Parametric Equations 1 Answer Wataru Sep 7, 2014 Since #x^2+y^2-25=0# is the equation of the circle centered at the origin with radius 5, its corresponding parametric equations are #x(t)=5cos t# #y(t)=5sin t#, where #0 leqt < 2pi#.
