Nice! Some readers may wish to also check out the built-in
graphing calculator of The vOICe Learning Edition, toggled
on and off by function key F8. Its functions are described
on the web page at the URL

   http://www.seeingwithsound.com/winmath.htm

Whatever is not covered by the calculator functions may
be covered by screen sonification of the graph windows of
powerful math packages like Mathematica and Matlab.

Best wishes,
