The steps for defining a parametric graph are similar to the steps for defining a function
graph. Chapter 4 assumes that you are familiar with Chapter 3: Function Graphing.
Chapter 4 details aspects of parametric graphing that differ from function graphing.
10. Press
s
. The plotting action simultaneously
shows the ball in flight and the vertical and
horizontal component vectors of the motion.
Note:
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.
