<p>Will being very familiar with the TI-89 Titanium pretty much (not entirely) ensure one an 800 or near it?</p>
<p>That's what I have heard. There are five questions (about) on the test that can't be answered without a calculator. The TI89 allows for the quickness needed to do 50 questions in 60 minutes. By having the formulas pre-programed into the calculator you have time to actually finish the problems.</p>
<p>Hm. This interests me. What exactly is the difference between the TI-89 and the TI-83? And how can this help us better when taking tests?</p>
<p>Edit// As a matter of fact, they look almost identical. Would my teacher be able to recognize the difference between the two if I get a TI-89 instead of a TI-83?</p>
<p>TI89 has the ability to store formulas. So long as you know how to use it well and access the formulas it will give you the ability to work faster.</p>
<p>do you really even need formulas? if so which ones do you need to have</p>
<p>Is that not cheating? If they wanted us to have formulas they would have given it to us...Are you sure it's not against the rules and that we can use the TI-89 for this purpose? Because it effectively means we don't have to memorize any of the formulas..</p>
<p>i have no idea what everyone is talking about formulas...i was just talking about typing something into the ti-89 and getting an answer, like most reduced, etc.</p>
<p>Look at the college board web-site. The reccomended calculators include the TI89, and no it is not considered cheating. A part of the test is to see if you know how to properly use a calculator to your advantage.</p>
<p>so voiceofreason, do you think the 89 can carry one to get near an 800</p>
<p>Im a junior and in Dif Eq. I have an 89 and took the sat a couple monthes ago. I got a 740 cus i didnt remember what a median was and some other dumb problem. The 89 helps, but the 8th grade algebra definitions screw a lot of people over.</p>
<p>I have a ti89 but I do not know half of the things that I can do with it...does anyone have any tips or guides on how to use it for the math IIc.</p>
<p>All I really know how to do is the solve: button...</p>
<p>know how to type in the variables in and manipulate them with the home thingy</p>
<p>know expanding the inputted value</p>
<p>know how to graph (obvious)</p>
<p>know how to use the custom's f(X) thingy</p>
<p>Can you give me a quick explanation of these three items and how they pertain to the test? Thanks again</p>
<p>know how to type in the variables in and manipulate them with the home thingy</p>
<p>know expanding the inputted value</p>
<p>know how to use the custom's f(X) thingy</p>
<p>like make sure you know how to type x, y, etc into the calculator so that when you press enter it will simplify your answer etc (usually works best with questions for like sin, cos, tan...)</p>
<p>home, f2, expand the simplified problem to get all the terms</p>
<p>custom, f2, 6 (define f(X)= ?) you can do this for other ones like g, just press 6 and delete f and put g</p>
<p>then do what you wanna do</p>
<p>in the titanium, is there a place that has the ellipse/hyperbola/circle formulas where you input values for the corresponding variable (I know the casio has some)</p>
<p>there're probably programs for them.. i know that even the 83 has a app for it, so the 89 must have something to that effect too</p>
<p>specifically though, shouldn't there be a preloaded one?</p>
<p>I don't think the TI-89 would have any effect on your score if you know your math. I used an 83 and got a 790 with time to look over my answers. If you use an 89, you'll probably spend your time looking for the formulas you put in it when it could be solved more easily conceptually. I wouldn't recommend an 89 until you hit calculus, the integral and derivative functions are a lifesaver.</p>
<p>Has anyone found a program for the 89? Is there something online?</p>
<p>The 89 would actually be a burden unless you know it like the back of your hand. There are similar calculator applications for the 83 that make the 83 just as efficient as the 89 when it comes to math IIC, instantly guaranteeing a 750+.</p>
