TI-83 Plus Parametric Graphing 157
10.Press s. The plotting action
simultaneously shows the ball in flight and the
vertical and horizontal component vectors of the
motion.
Tip: To simulate the ball flying through the air, set
graph style to ì (animate) for X1T and Y1T.
11.Press r to obtain numerical results and
answer the questions at the beginning of this
section.
Tracing begins at Tmin on the first parametric
equation (X1T and Y1T). As you press ~ to trace
the curve, the cursor follows the path of the ball
over time. The values for X (distance), Y
(height), and T (time) are displayed at the
bottom of the screen.
