<p>TI 83+ or TI-89 I've never used the TI-89, is it worth it to learn how to use it?</p>
<p>The TI-89 will not make the Math Level 2 any easier, especially if you are used to the TI-83.</p>
<p>I used a TI-84 (essentially the same thing) on my May test and everything went fine. No question was hard enough to warrant a more advanced calculator.</p>
<p>I have a TI 89 and its nothing really that special.</p>
<p>No point in learning a whole new calculator just for Math IIC. If you're taking AP Calc in the future, it might be worth your time, but unless you have 2-3 months to really get to know the 89, stick with the 83.</p>
<p>the 89 is a better calculator, but if you don't know, don't even risk it. I hope you have a solve function on your calculator. It really helps.</p>
<p>it 83 does not have a solve function
but 89 does!
and for calc and everything else 89 will be a lot better
the solve function on 89s can solve for x for any functions you put in there, saves you LOT of time on the SAT 2( i mean you only get 60 minutes for 50 problems. the solve function alone can probably save you atleast 5 minutes. so more time to work on the other problems that you didn't get ) and less chances for stupid mistakes
and its supposedly a bit faster
89 all the way
but you don't have much time to learn it. so iono</p>
<p>I think i'll bring my 89 for solving. How do I use the solve function?</p>
<p>for titanium its
go to home->F2, the first one. so after you press F2 either press enter or 1
the "solve("
will show up
solve(the function,what to solve for)
so like
solve(0=X^2+2x+1,1) gives you x=-1
you have to have the thing to equal something, normal its 0
but for trig functions
trying graphing it and tracing it just in case you leave out some answers
PM me for more questions!</p>
<p>I used 83 and did just fine, so you don't need the 89 at all, especially if you're unfamiliar with how to use it.</p>
<p>anyone get perfect score with 84?</p>
<p>Use the calculator you know better... a fancier calculator won't help you if you're not familiar with it. TI-83+ worked great for me.</p>
<p>Getting a perfect with a 83+ is not hard. And, 83+'s do have a solve function. Even if you don't know how to use it, you can still graph the function and see where it intersects the value that your looking for.</p>
<p>TI 84 Silver works for me :)</p>
<p>solve(0=X^2+2x+1,1) gives you x=-1</p>
<p>Should be: solve(0=X^2+2x+1,x)</p>
<p>The TI-89 is excellent. I like the format much better than the other TIs. Once you learn how to use it, you'll like it a lot.</p>
<p>use the calculator you know better. however, if you know both equally well, ti-89 is better in the sense that it has a solve function and other things like factoring and that sort of stuff. however, if you don't know how to use it, use your ti-83</p>
<p>Sheed30, i got a perfect score with an 83+</p>
<p>Thank you, just making sure it's a possibility.</p>
<p>is it absolutely impossible to take the test without a calculator? I lost my 89, broke my 84, and my old 83+ stolen? i know its a stupid question. i just want to share my agony.</p>
<p>How do you solve on the 83+?</p>
<p>I know that you are permitted to program stuff in your calculator for the exam, but what type of stuff should you program in to make doing so useful?</p>
