The math teacher and the calculator.

I am so getting sick of Professors, who dock me because I actually forked out the cash to get a decent calculator. My new Calculus professor has decided I can't use my TI-89 for her tests because the TI-89 can perform certain functions that the more common TI-86's and TI-83's cannot perform. This decision of course comes just days before one of the midterms. So now I have to borrow a calculator from the library to use during the test. Well I don't know if you know the difference betweeen the interfaces of the TI-86 and the TI-89, but lets put it this way: It like the difference of playing a FPS on the XBox and one on the PC. My TI-89 is way more flexible, has more functions and is more user friendly by a long shot.

The WORST part is that while digging thru the instruction for the TI-86 that I will have to be using, I found out that it does in fact have the functions that caused my professor to decide to ban my TI-89. They are just a different style of input, which not as easy use! So all those TI-86 users in my class, who really know their calculators are probably breathing a sigh of relief that she didn't ban theirs too. Cause then we'd all have to use $5 casios that don't even do logs...
