Differential Equation Graphing 441
Ê Important: Change tstep from .1 (its default) to 1. Otherwise, BldData calculates too
many rows for the data variable and a Dimension error occurs.
6. In the Window Editor (8$), set
the Window variables.
Ê
t0=0.
tmax=100.
tstep=1.
tplot=0.
xmin=
L1.
xmax=100.
xscl=1.
ymin=
L10.
ymax=10
yscl=1.
ncurves=0.
diftol=.001
7. In the Home screen "
H8"
use
BldData to create a data variable
containing the
RK graphing points.
8. Return to the Y= Editor, press:

Set Solution Method = EULER.
Note: You do not need to graph the
equation before using
BldData. For more
information about
BldData, refer to the
Technical Reference module.
9. Return to the Home screen, and use
BldData to create a data variable
containing the
Euler graphing points.
