Defining and Displaying Parametric Graphs

TI-84 Plus Graphing Mode Similarities

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

(distance),

(height),

and

(time) are displayed at the bottom of the

screen.
