13-5 Dynamic Graph Application Examples

Example To use Dynamic Graph to graph the parabolas produced by balls

thrown in the air at an initial velocity of 20m/second, at angles of

30, 45, and 60 degrees. (Angle: Deg)

Use the following View Window parameters.

Xmin = –1 Ymin = –1

Xmax = 42 Ymax = 16

Xscale = 5 Yscale = 2

With the initial velocity defined as V and the angle defined as

, the parabolas can be

obtained using the following expressions.

X = Vcos

Y = Vsin

T – (1/2)gT

g = 9.8 meters per second

1. Input the functions, making sure to specify them a parametric (Param) type.

2. Display the coefficient menu and specify the dynamic coefficient.
