Press } Í Í to change the graph style to ë for X1T and Y1T. (These keystrokes assume that all graph styles were set to ç originally.) 10. Press p. Enter these values for the window variables. Tmin=0 Tmax=5 Tstep=.1 Xmin=L10 Xmax=100 Xscl=50 Ymin=L5 Ymax=15 Yscl=10 Note: You can check all WINDOW variables, including @X and @Y by pressing  1:Window. 11. Press s. The plotting action simultaneously shows the ball in flight and the vertical and horizontal component vectors of the motion. Note: To simulate the ball flying through the air, set graph style to ì (animate) for X1T and Y1T. Chapter 4: Parametric Graphing 92
