400 Chapter 23: Activities
This activity uses the split screen settings to show a
parametric graph and a table at the same time to study the
flight of a hit baseball.
Perform the following steps to study the flight of a hit baseball that
has an initial velocity of 95 feet per second and an initial angle of 32
degrees.
1. Set the modes for

3. In the Y= Editor on the left
side, enter the equation for the
distance of the ball at time
xt1(t ).
xt1(t)=95ùtùcos(32¡)
