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.
