I have a TI 30 and a TI-89. The TI-30 does logs, ln, exponentials, sin, cos, and tan. My instructor informed me that I can not use the TI-89 on tests. I am thinking of spending the $120-ish for the second calculator, but I'm not sure. The first test is this week. If it raised my test scores (plural), like 3-5% it would be worth it. I'm not at all familiar with it; what important (every day) functions does the ti-84 do that the more basic TI-30 does not? Incidently this is Calc 1 and I still need to go through Calc 3.

Definately buy the TI-83 (you can get them second hand on e-bay for $20-$30). You'll need it if you continue in Math. The TI-30 doesn't let you see the graph of a function like the graphing calculators do. Depending on your teacher, you may also learn how to find intercepts (where a function hits the two axes or where two functions intersect each other), minimum/maximum values (a BIG theme in Calculus), and other stuff like matrix manipulation.
Incidentally, the TI-83 and the TI-84 are pretty much the same calculator. the TI-84 came out a year or so ago, but is just "cooler" (and therefore more expensive) than the TI-83.
I would see what you can find on e-bay or other second-hand sources.

The Ti-30 is just a regular calculator it is not a graphing calculator like the Ti-89 and Ti-84. The Ti-89 is the best calculator out of the three by far because it does just about everything you will need. Now I'm not going to recommend you go and break the rules but how large is the class? Scratch that you already talked to your prof so he probably will have his eye on you. Ask him how much graphing will be involved on the test it would probably help your score the 3-5%

Wait, why won't your teacher let you use a TI-89 on a test? My Calc teacher recommends it. I've been using a Casio for the past 4 years but I have to upgrade soon. TI-89 is somewhat complicated but what it does is that when you are calculating limits it can give you an exact answer or a symbolic one. That is just one example. Maybe your teacher knows that TI-89's could let you do too much of the math by calculator but this is CALCULUS! It's not always possible to do the math by hand.

I would recommend the TI-89. Most profs who don't allow the 89 don't allow any graphing calculator at all. It's a great calculator though because it has a computer algebra system which allows you to calculate answers exactly. For example, if your answer is 2pi, it will tell you the answer is 2pi rather than the decimal approximation. same thing with square root, etc. If you're going to invest in a calculator, I'd recommend the 89

I have two viewpoints:
1. I never used a calculator in math. I did it all on paper or in my head. I could make a test extremely hard and you'd still never need to use a calculator--it'd just be hard. So I'm still not a fan of calculators.
2. Like I just said, I could make a test extremely hard, with or without calculator usage. What's your teacher afraid of, letting you use whatever calculator you want? Bah.

Everything. You can program it to do derivatives, integrals, play tetris....
It can do whatever you prgram it to. It's useless unless you know how to use it though.
It can graph too.
