<p>I am planning on takin the IIC and I currently have a ti-83 (non plus). I could probably borrow a ti-89 from my math teacher, and I am wondering if it is worth it to, compared to walkin in with a ti 83. If i have time to screw around with the calc and a book to teach me the calc functions, should I go for it?
If yes please direct me to a book or website with info on how to use a 89 for the test.
thanks</p>
<p>No, no, no, NO, NOO!!</p>
<p>Good lord. </p>
<p>Use your own calculator!</p>
<p>why not ??? It took me only 3 to 4 days to get familiar with Ti-89. It's far more powerful than the TI-83 !!! Go to <a href="http://www.ticalc.org%5B/url%5D">www.ticalc.org</a> and get great programs for your Ti-89.</p>
<p>use what you are familiar with..</p>
<p>I think the TI-89 takes a while to get used to - although it is <em>so</em> powerful, it is much better to take the test with a calculator you are absolutely, 100% comfortable with.</p>
<p>use what you are familiar with. However, i think that if you can get use to the basic functions of the 89, go for it. You still have two weeks(?)- enough time.</p>
<p>why not use both?</p>
<p>well, make sure you use it A LOT before the test. and try to get your hands on a manual. do a practice test with it too.</p>
<p>Definitely borrow one, but make <em>sure</em> you bring a calculator you're more familiar with. Practice up on the 89. I've had mine for a while, and I STILL get wrong answers when I try to find a point of intersection for two lines. I haven't figured out how to properly use that feature, so I just switch over to my 89. I bring both to school everyday, and I always use both.</p>
<p>use one you're comfortable with . . . personally, i haven't really used the 89 so i opted for the 83 and I did great on the test.</p>
<p>USE THE TI-89 but only if you buy it right now and practice everything on it. You must know exactly how to use it cuz come test day you'll be spending an hour entering a trig funtion into it. It is extremely powerful and if you're gonna buy it fish out 50 more dollars and buy a TI-89 Titanium which will be very useful later for college.</p>
<p>I think its pointless. A calculator is not going to make you better at math.</p>
<p>Of course a calculator won't make you better at math, but if you know how to use it properly, those calculators make finding zeroes and looking at graphs such a piece of cake ...</p>
<p>i agree with tero, if u dont know your math a calculator is going to be of little help. besides, there aren't many problems on IIC where the 89 is going to be better than the 83</p>
<p>I have lots of time till the test, probably going to take it in june. I am just wondering about the amount of problems that can be solved (or more easily) on a 89 compared to a ti 83. I'll ask my math teacher about it. Can someone post a problem that there is a difference in solving it with the different calcs?</p>
<p>Edit: I am currently in a precalc 11th grade class. (Seems like everyone on CC is in AP calc in 11th, and I am in the higher class, but next years is AP AB calc) Should I take the IIC jan 20 if I can prep with barron's sufficiently?</p>
<p>Tons of people get 800's with an 83. Using a calculator you're unfamiliar with (which you will be, even if you say you're going to practice) just going to put you at a disadvantage.</p>
<p>You don't really need an 89 for this test...heck, you don't even need a graphing calculator. Use whatever you use the most, however, so you don't waste time figuring out how to use it.</p>
<p>Ti-89 is so complicated, just got it and i don't even know how to graph circles. I am returning it!!!</p>
<p>Ashernm, you'd be fine with an 83, just as long as you take the 2C after you complete Precalc. I took it in november with 83 and got an 800. Either way, prep for the test alot and you'll be fine.</p>
<p>What does an 89 have that is all that helpful for IIC?</p>
