[Blindmath] Graphing-calculator?

[stine skovbon]

Hi all!
I study math, not on university level, but I have a problem anyway.
What are you using to compensate for a graphing-calculator? (hehe,
maybe the wrong word!).
Do any of you use TI InterActive together with JAWS? (I've JAWS 12).
Or do you know if it's somehow posible to connect a Texas TI-89 pocket
calculator with a braille display (I use a HumanWare Brailliant
display).
I really hope to hear from you and thank you in advance! :-)
Best regards from Stine
