In calculus, a parametric derivative is a derivative of a dependent variable with respect to another dependent variable that is taken when both variables depend on an independent third variable, usually thought of as "time" (that is, when the dependent variables are x and y and are given by parametric equations in t). == First derivative == Let x(t) and y(t) be the coordinates of the points of the curve expressed as functions of a variable t: y = y ( t ) , x = x ( t ) .
