You can certainly graph inequalities on the TI-89, although you have to
know whether you want above or below the function. You can't use the
inequality per se, but in the Y= window there is a menu choice (F6) of
Style and 7:Above or 8:Below will graph inequalities.
Does that help?

I want to find out how to graph inequalities using the TI-89. On a
TI-83, 84 or 85, when you put in an equation and use the test key to get
the inequality sign, the graph shows up when you press graph. I can not
make the TI-89 do this. If anyone knows how, I would appreciate your
help.

One more thing about graphing calculators. A wonderful simulator for
your desktop is available at:
=20
http://ciw.asd.wednet.edu/~jbassett/ti/=20=20
=20
Install into a folder. Click on the vti.exe file. If you get a screen
that asks you to look to search for a ROM image, press cancel, then
click on the vti.exe file again.

I have this running from a thumb drive which is something I cannot do
with my copy of TI SmartView. As I teach in different classrooms in
different buildings,and use a projector with PowerPoints for many
lessons, this is a fabulous tool for teaching, but also for your online
students. I don't have to drag my Viewscreen with me and hope the
overhead has a working bulb, and I can make it bigger or smaller, and
have options for different views. I can leave it "on top", take screen
shots, etc. Right click for many options. ( Silly thing, you have to
click to ON button to start it - just like real) The kids love that I
am showing them what keystrokes along with how to use the Calculator
effectively to enhance the lesson.
=20
Also, since this can be made very large, it might be a wonderful tool
for those of you with visually impaired students.=20
