Peter,
I don't know if you've experienced this, but sometimes people with  
vision overestimate how much they use it, especially for things like  
this. One-line displays are ok for math, unless equations are longer  
than the display itself. Graphs are another matter, but I don't think  
there's a way to make those work with electronic means anyway. You'll  
have to get someone to create them with stickywick or other craft-like  
material. Most higher-level maths don't use graphs anyway, because  
they work in n dimensions. Braille displays the size of a full sheet  
of paper would certainly make navigation between equations easier, but  
I don't think they'll be available for some time.
Did you look at those links I sent you? What did you think? There's  
been lots of talk of R as well. Use it for statistics mainly. Also,  
Math Type from Design Science is an easy way of writing things in  
LaTeX and having them translated to math symbols instantly. Thanks to  
others on this list I have that info; I definitely wouldn't otherwise.  
Have you decided how you will learn the material? Audio or Braille or  
LaTeX or other systems? How do you want to submit your work for  
marking? If you can narrow it down it'll make things more manageable.
