Tips for Beginners for the TI 89 Calculator

Parametric Graphs. To make a . parametric graph. key MODE Graph = 2: parametric. A parametric graph is made on the x-y axes by defining x = f(t) & separately y = f(t). Thus in parametric mode, you must type in a pair of equations. E.g. in Y= xt1 = sin 2t. yt1 = sin 3t. To view the graph of the above set x & y min/max = ±1 & use radian mode. ................
