To solve, press:

@SOLVE (wait) @EDIT@. The result is 0.2499 ≈ 0.25. Press @@@OK@@@.


Solution presented as a table of values
Suppose we wanted to produce a table of values of v, for t = 0.00, 0.25, …,
2.00, we will proceed as follows:

First, prepare a table to write down your results. Write down in your table the
step-by-step results:

t v

0.00 0.00
0.25

… …

2.00


Next, within the SOLVE environment, change the final value of the
independent variable to 0.25, use :
