4. Repeat step 3 to create three more pairs of equations using the heights

1.00

1.50

, and

meters.

5. Press

9.8) Xmax = 2 Ymax = 2

Tstep = .01 Xscl = .5 Yscl = .5

6. Press

and select

ZSquare

adjusts the

WINDOW

variables to include the viewing

WINDOW

you specified, while

providing a realistic (proportional) visual representation of the water

jets. It then graphs the trajectories of the water jets from the 5 chosen

heights. What height seems to provide the maximum distance for the

water jet?

7. Use

TRACE

to determine the distance from the reservoir where each

water jet hits the next pool.

8. Where would you place the holes to construct a fountain that you find

visually interesting?

9. Can you think of a way to construct the problem to show two levels of

fountains?
