Repeat for t = 1.25, 1.50, 1.75, 2.00. Press @@OK@@ after viewing the last result
in @EDIT. To return to normal calculator display, press $ or L@@OK@@. The
different solutions will be shown in the stack, with the latest result in level 1.
The final results look as follows:

Graphical solution for a second-order ODE
Start by activating the differential equation numerical solver, ‚ Ï
˜ @@@OK@@@ . The SOLVE screen should look like this:
Notice that the initial condition for the solution (Soln: w Init:[0., …) includes
the vector [0, 6]. Press L @@OK@@.
Next, press „ô (simultaneously, if in RPN mode) to enter the PLOT
environment. Highlight the field in front of TYPE, using the —˜keys.
Then, press @CHOOS, and highlight Diff Eq, using the —˜keys. Press
@@OK@@. Modify the rest of the PLOT SETUP screen to look like this:
