WebFeb 22, 2024 · The parametric equations of a circle of centre (0,0) and radius r are; x = rcost y = rsint This can easily be verified, as: x2 +y2 = (rcost)2 + (rsint)2 = r2cos2t + r2sin2t = r2(cos2t +sin2t) = r2 ( ∵ cos2t +sin2t ≡ 1) And so the parametric equations of circle centre (a,b) and radius r are simply: x = a +rcost y = b +rsint WebThe parameter is an independent variable that both x and y depend on, and as the parameter increases, the values of x and y trace out a path along a plane curve. For example, if the parameter is t (a common choice), then t might represent time.
