[Athen] Math Lab accessibility

Sorry I should have been less generic with my comments. The MathTrax
program was designed for high school rocket telemetry functions. It
was never designed for students at the University level. It is also
from my experience not completely reliable with what can be read in
the UI. As far as the AGC from View Plus goes It is not as complete
as a TI-80 series calculator. But of course costs three times the
TI-83. The feature where you can read the table of results is nice.
One thing that I think that it is missing is the ability to follow the
curve of the graph by moving a cursor and getting the XY coordinates
while you move the cursor up and down or back and forth along the
curve. This is a powerful function in the TI-80 calculators. The
feedback for the Find Intercept is Kind of clumsy and difficult for
students to read. At Cleveland State most of our heavy use of
graphing calculators is in the business program. These programs fall
short of meeting the requirements of a graphing calculator for
business or engineering. Since the TI-80 calculators are not in
anyway accessible for blind students, for some work they will have to
make due.
