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 X
1T
and Y
1T
.
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 ( X 1T
and Y 1T
). 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.
