<p>I have a TI-83 silver edition, but I've heard that the TI-89 is a whole lot better? What makes them different? and I thought you could take the Math IIC without a calculator.. 0_0</p>
<p>TI 83s uses a lot of calculator syntax while the TI 89 uses programming syntax. It's a bit more like a computer like when you execute some command, its like executing method with explicit parameters. Whatever you're comfortable with I guess.</p>
<p>To get to the point, no you don't need an 89.</p>
<p>I used a TI-83 silver and got 800 on IIC, so I'd agree and say that an 89 is not necessary. You probably don't want to waste time learning how to use one, either. It's pretty confusing when you first start out.</p>
<p>And, correct me if I'm wrong, but I think it's the SAT I Math sections that you can complete without a calc.</p>
<p>Use whatever you've been using for a while. If you go out and get a new calculator the morning of the exam you won't be able to use it efficiently. Your math teachers have probably told you this before, but it's entirely true: your calculator is only as smart as you are - it's just a lot faster. And no, the TI-89 is not noticeably faster than the TI-83, so there is no benefit for this exam.</p>
<p>you really dont need ur calc cuz there arent really complex problems
i used the 89 and got an 800 but i probably cud have used like a ti 34 and still got the same score</p>
<p>Its the sat 1 math that requires no calc (Advised that you use it though...)</p>
<p>Most of the time, you can do all the math on the SAT I without a calculator. It's more of a reasoning test than a math test. As such, most problems can be reasoned through so little math needs to be done. </p>
<p>Too bad I can't do this...</p>
<p>An 89 could help. It has a lot of functions that an 83/84 doesn't ... and it wouldn't be a bad idea. If you're going to be confused, though, it might be bad, but it can seriously help ...</p>
<p>what functions does the 89 have which help on the test?</p>
<p>okay, lets say you have a cubic equation and you want to solve for its zeroes (idk that sounds like a typical problem, right?) or factor it or whatever else you're in the mood to do. The 89 will do it ... simply type
solve(blahx^3+blahx+2 ...........=0,x) .. and it will give you something like
{2 , sqrt(5) and 3 }
which is much faster, easier, and accurate (sqrt 5 vs an approximation) ...
it will also factor .... which is nice :)
it does sigmas too .. which are a lot nicer to type in on an 89.</p>
<p>NOOOOO I know people who get an 800 with a scientific. The question is: how much do you want out of your calculator? And you know the answer better than everyone else</p>
<p>89 bascially has shortcut mechanisms... i guess</p>
<p>Forget the type of calculator, you really don't even need one. I used my calculator perhaps once or twice to double-check my work, and still ended up with an 800. Remember, the College Board isn't trying to give "richer" students who have graphing calculators an advantage, so I don't think you'll have questions on roots that require much work. Sometimes, using a calculator requires more time than using your brain.</p>
<p>Just take a scientific "just in case." (better to lose $16 than $100+)</p>
