Drawing a Dynamic Graph 13 - 3
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
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.
