Unformatted text preview: 2 y x = x parabolic function t Circle: If we let t = the angle, then: cos sin 2 x t y t t = = Since: 2 2 sin cos 1 t t + = 2 2 1 y x + = 2 2 1 x y + = We could identify the parametric equations as a circle. Graph on your calculator: Y= xt1 cos( ) t = yt1 sin( ) t = WINDOW GRAPH 2 Use a [4,4] x [2,2] window. Ellipse: 3cos 4sin x t y t = = cos sin 3 4 x y t t = = 2 2 2 2 cos sin 3 4 x y t t + = + 2 2 1 3 4 x y + = This is the equation of an ellipse....
