<p>Hello All,</p>
<p>Well I'm using a TI 84 (contemplating on buying an 89 before saturday) at the moment and was wondering for those of you who took or are taking the exam, if imputing formulas in your calculator actually helps. </p>
<p>If it does can anyone recommend maybe a good program to download onto it or a good list of formulas that really may make a difference?</p>
<p>shoot I just realized I put this on the wrong board</p>
<p>Quadratic, Distance, Heron's, Brahagupta's, and Law of Cosines.</p>
<p>On the actual test I used Distance in 3-D, Quadratic, and Heron's....</p>
<p>I would not recommend getting a TI-89 for Saturday because it is only useful mainly for calculus which is not on the test except for limits. Also, it will be very tough to learn how to use it in two days now left. The programs will really not help you that much, I used a TI-83 plus without any programs and got a 800.</p>
<p>Don't buy a TI 89 right before the test. You probably don't know how to use it. Use the calculator you are the most familiar with.</p>
<p>dude u dont need a TI -89
and plus the math IIC is an easy test</p>
<p>ok...2 days left...and i don't know how to use "any" graphing calculator...
(and i m terrible at functions !)
sounds like i m heading towards disaster...with just a scientifique calculator</p>
<p>^That may be a problem..</p>
<p>well wat do u suggest... ?</p>
<p>well wat do u suggest... ?</p>
<p>^ Write some programs for the formulas....</p>
<p>If you want to get a TI-89, you should definitely learn how to use it.</p>
<p>I'd reccomend the TI-84. It's much easier to learn and is more helpful with the statistics stuff that you may encounter.</p>
<p>What are you guys talking about?
TI-89 is a lifesaver!</p>
<p>It took me around a week to get used to it.
You only need to be familiar with the graph function and the algebra functions.</p>
<hr>
<p>DO NOT use a scientific calculator. You will need the graph functions on the graphing calculator to quickly find intersections.</p>
<p>Well...the only thing thats really turning me on to buy an 89 is the Find x function. </p>
<p>That could save precious minutes no?</p>
<p>Would I be allowed to bring both calculators to the test room?</p>
<p>^ Yes, apparently the expand, solve is particularly useful. </p>
<p>For example, you can put in</p>
<p>x^2 + 6y^2 = 10 -> then you can find the inverse with the TI-89 symbolically. (Ti-84 cannot do this)</p>
<p>I used both in the testing room, so I assume you can use both. But! ou can' use two at the same time</p>
<p>I HAD NO PROBLEM USING A SCIENTIFIC CALCULATOR</p>
<p>yes, there were those couple of questions that looked like it wud be easier and more comfortable to solve using a graphing calculator....but i just left them.
I still can't believe i freaked out the night before for no reason.
besides, the invigilator didnt allow us to use 2 calculators....he said use either one.</p>
<p>P.s. 800! :D</p>
