Example The path over time T of a ball thrown in the air at initial velocity V and
an angle of θ degrees from horizontal can be calculated as follows.
X = (Vcos θ )T, Y = (Vsin θ )T – (1/2)gT
Use Dynamic Graph to plot the path of a ball thrown at an initial
velocity of 20 meters per second, at horizontal angles of 30, 45, and 60
degrees (Angle: Deg).
Use the following V-Window settings.
Xmin = –1,
Ymin = –1,
T θ min = 0,
