TI calculators are faulty. Get yours replaced.

Damnit, I may have been affected by this problem. Apparently, some log() or ln() functions return faulty answers. I believe the TI 30 line, TI 40 and TI 34 line are affected. My university does not allow graphing calculators but I don't believe these are affected.

Anyhow, here's the link [L]http://www.ti.com/calc/docs/statement.htm[/L].

Pretender,

How'd you mess up your TI 30? I've got a TI 30X IIS and it literally died on me for no reason (checked the battery...wasn't the problem).

I used to keep it in my backpack (in the section which is all the way behind you). If you take New York City subways, you begin to realize it's a bad idea. I dunno exactly when it happened, but the LCD probably took too much damage over time and some digits wouldn't display correctly. I tried to open it up to fix it, and that further magnified the problem.

Luckily I had just gotten my TI-89 a few days earlier, unfortunately we can't use them on physics exams, so I'm hoping to get my TI-30 replaced thanks to this offer.

I'd love to use a real graphing calculator. No Canadian high schools or universities allow them though. In fact, they frown upon calculator usage and try to make the exams and tests so you don't need them. But, it's my security blanket and I definitely want my TI 30X IIS going into my exams in a few weeks.

Ah, things are much different in the USA. Students are expected to be too stupid to figure out fractions like 80/240, so we're allowed calculators on almost all tests.

Glad I bought my daughter a TI-89. Which really rocks by the way. I've been reading the handbook for the last few days and am quite impressed at the array of functions. Matching what the calculator will do with the SAT math questions I've seen suggests it may be helpful on as many as 10 questions.

By the way, to those who say no Trig on the SAT-WRONG! In 5 practice tests I've found 5 trig questions. Simple ones though.
The hard questions seem to be the number theory and geometry questions.
