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
