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

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.
