Parametric Equations To represent motion in the xy plane, let x = f ( t ) describe the horizontal motion and y = g ( t ) describe the vertical motion. x = f ( t ) y = g ( t ) parametric equations of a curve with parameter t . Cartesian equations only contain x and y terms such as y = x 2 or x sin y + 3 y - x = 4 . Parametric equations enable us to graph curves that are not functions. ex. x = sin(2 t ), y = cos(3 t ), 0 t 2 p
ex . x = - 2 + t , y = 3 + 2 t , - 3 t 3 ex. x = - 2 +
