Slopefields for the TI-82/83
-- a program --
Given a differential equation, say y' = 3x-y, this program will make the
TI-82/83 draw a slopefield for that differential equation.
The program is available in two formats.
A binary version that you can load directly
into the graphlink program and download to your calculator. NOTE:
If you have trouble downloading this, try holding the shift button on your
keyboard when you click on the link.
A screen shot for those typing in by hand.
Directions for use:
1.We must translate the differential equation: In place
of the function (y in this case), write Y (upper case), in place of y'
write Y1,
and in place of the variable (x in this case),
write X. So for the example y' = 3x-y we translate to: Y1=3X-Y.
2.Now press [Y=] and enter our differential equation from
the last step on the first line:
3.Press [WINDOW] to select a suitable window or range.
4.Press [PRGM] and select the SLPFE program. Press
[ENTER]once to paste prgmSLPFIELD on your text screen;
press [ENTER] again
to run the program.
