time t = 2, the input form for the differential equation solver should look as
follows (notice that the Init: value for the Soln: is a vector [0, 6]):
Press
@SOLVE
(wait)
@EDIT
to solve for w(t=2). The solution reads [.16716… -
.6271…], i.e., x(2) = 0.16716, and x'(2) = v(2) = -0.6271. Press
@CANCL
to
return to SOLVE environment.
Solution presented as a table of values
In the previous example we were interested only in finding the values of the
position and velocity at a given time t. If we wanted to produce a table of
values of x and x', for t = 0.00, 0.25, …, 2.00, we will proceed as follows:
First, prepare a table to write down your results:
Next, within the SOLVE environment, change the final value of the independent
variable to 0.25, use:
