I am actually coursing the Maths High Level, IB Diploma, on high school
and I am very intereted in buying the TI-89 for this reason. However, it
seems that this calculator is not permitted in this course, we can only use
Texas Instruments calculators until the TI-86. What can I do?, Can you do
anything about it?.
Thanks for your help.
Bye
