SOURCE: Parametric Graphing of Inverse Functions
if your looking to make a parabola out of it add
X3:T²+T
Y3:-T
X4:-T
Y4:T²+T
Those functions are not parabolas. since T² cannot be negative since negative times negative = positive. (unless it's an imaginary number, but thats a different story)

At first, you have to use t symbol for parametric functions when you operating with TI 89 Titanium. In your case you must input your relations as x1=3cos(t) and y1=2sin(2t). Then graphing it. See captured image
