***～会飞的蝎子～学习宁静致远

The latest version of ti-calculator right now is: ti-nspire.
1. The following is the link for the reference Guide, where describe all the functions::

Note: invF is included in the latest version, but invbinomial is still in blank...

2. I am very glad there is a similar software version for the calculator, which support me to use my computer like a calculator.  I know this is kind rediculous, but it is true for me. Always, easier to use computer than calculator and always, calculator will get special permition in the exam and computer not. 


3. It is really cool from the outlook: You will have the choice of two keyboards.
