Hi Brian,
You're the *only* person who responded who was familiar with the app,
so I definitely appreciate your input. I'm trying to help a math
teacher, so I, myself, am not a geogebra expert.
She is new to teaching, and they suggested she put Geogebra on her
equipment. So, I loaded it onto her brand new Mac Air (after fumbling
about with the controls far too long to believe the "it just works"
mantra) and then I put it on her iPad, neither of which was a problem.
I put it on my Linux machine, and then on Windows, neither of which
had a problem. The only problem was on her cellphone, and then, as
a test, on mine.

Since Geogebra is now on her iPad, the only devices left are the phones.

You hit the nail on the head. She plans on using it for teaching, so,
she will plug her Mac Air laptop into some kind of VGA adapter that
they gave her, and she will display it.
She just wanted to practice, at home, on the iPad and Android phone.

The problem with teaching high-school math, as I had explained to
this math teacher, and as I see it, is that it never makes any pragmatic
sense to the kids.
That is because math teachers, as a rule (but not all), love math
for math's sake. But, very few kids will be theoretical mathematicians,
who love math purely for the sake of math. If math isn't used as a tool,
then the kids don't get it.
They never get practical math.
Math never has a lab. Physics has a lab. Biology has a lab. Heck, even
cooking has a lab. But not math.
It's just taught wrong. Anyway, the point of the graphing software is to
at least *show* what the lines mean.
What I also looked up, for this teacher, is PRACTICAL uses of Algebra I
and Algebra II. Examples. Examples KIDS would care about. Like the equation
of a football on a ballistic path. Or the speed of an arrow shot from a bow.
My opinion is that a math equation should NEVER be on a page without
a real-world application of that exact equation.

That's interesting because we were not attempting to get the geogebra
app on the kids' phones, but that would be a great idea, once we figure
out how to do it!
Thanks for the great insight!
