1. Set the modes for
Page 1 as shown in this
screen.
2. Set the modes for
Page 2 as shown in this
screen.
3. In the
Y= Editor on the left side, enter the
equation for the distance of the ball at
time
t for xt1(t).
xt1(t)=95†t†cos(32¡)
Note: Press 2 “ to obtain the degree
symbol.
4. In the
Y= Editor, enter the equation for the
height of the ball at time t for
yt1(t).
yt1(t)=L16†t^2+95†t†sin(32¡)
