Drawing a Dynamic Graph

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 T θ min = 0
Xmax = 42 Ymax = 16 T θ max = 6
Xscale = 5 Yscale = 2 pitch = 0.1
With the initial velocity defined as V and the angle defined as θ, the parabolas can
be obtained using the following expressions.
X = Vcos θ T
Y = Vsin θ T – (1/2)gT 2
g = 9.8 meters per second
1. Input the functions, making sure to specify
them a “ Param” (parametric) type.
2. Display the coefficient menu and specify the dynamic coefficient.
