Solve for the velocity, v0. (You solve for a variable by pressing

!and then the variable’s menu key.)

!*!!!!!!V0!!!!!+

Recall the range, R, divide by 2 to get the halfway distance, and enter that as the x-coordinate. Notice that pressing the right-shifted version of a variable’s menu key causes the calculator to recall its value to the stack. (The small square next to the R on the menu label indicates that it was used in the previous calculation.)

Step 6:

Solve for the height, y. Notice that the calculator finds values for other variables as needed (shown by the small squares) in order to solve for the specified variable.

!*!!!!!!Y!!!!!+

Enter the new value for the elevation angle (30 degrees), store the previously computed initial velocity (v0) and then solve for R.
