<p>I have a Ti-83 right now. Do you think I will need a Ti-86 or 89 in college. If so, which one should I get? I don't want to shell out extra money if I won't use the extra functions.</p>
<p>Unless you're pursuing a degree in math, engineering, etc., I think a Ti-83 should meet most of your needs.</p>
<p>In any case don't get the ti 86. That thing is just outdated.</p>
<p>is it true most math and physics classes don't let you use 89s? If so, based on your experiences, what calcs are permitted?</p>
<p>Most don't care what calculator you use, as for your homework for upper level math and science courses they assume you're going to use Matlab or Mathematica anyway. For the lower down ones, the courses are typically designed so there's no calculator advantage and in most places if you, say, use the 89's integral function on your calc II test it will be considered a violiation of academic integrity. That or you won't get full credit for not showing your work!
So yea, in short it doesn't really matter; I'm a science student and my trusty 83 has served me well.</p>
<p>ti-89 is the god of all calculators, if you can afford it, it is well worth it, especially for math/physics courses</p>
<p>at most schools you can't use calculators on math/physics exams, they test you so can show that you know the material, not how to use a calc</p>
<p>the 86 is pretty much uselesss, 83 is a much better calc (unless you like unit conversions)</p>
<p>TI89 is required for our school's calc BC class... dunno if that's because the teacher favors it though</p>
<p>for most theoretical math classes you won't be using a calculator, but if you're doing engineering mathematics, i suggest you get the 89</p>
<p>I have a TI83+ and have never needed anything better. My premed calc-taking boyfriend used by calculator for all his mathematical needs and also didn't need anything higher. I'd stick with what you have for now to save money, and if you find you need something better, then you can buy it.</p>
<p>ti-83 users always say that theirs is adequate enough, but that's because they have experience the awesomeness that is ti-89:) I love my 89 and really just can't stand the 83 interface, some love it. If you love your 83, you probably won't like the 89 initially because of all the differences, but it's really the better calculator. But in my experience 83 and 89 users are as hardcore as republicans and democrats, so try for yourself:)</p>
<p>Overall, Ti-89 is better. But, for statistics, Ti-86 is easier to use than Ti-89.</p>
<p>89>86>83 imo</p>
<p>The 86 has a better screen then the 83 - which has a screen I can't even stand to look at. Honestly I have used the 89 since sopohomore year - and before that I used a scientific calc for alg 2. (I don't remember if they handed out graphing calcs in that class or what). Whenever a friend asks for help and I look at the 83 screen I wonder how the hell they live with it. The 89 is worth it just for the screen imo...the 3D graphing and algebra calculator seal the deal. Plus it helps that I got mine for $30! MUHAHAHAHAHA. IMO since you can get an 89 for 140 anyday of the week....really there is no excuse not to get one if you are doing any math intensive major - even if it is just business or econ it would be worth it for the sharper graphs. You won't want to go back after you take one course with it.</p>
<p>why would a calc BC class require an 89, that's stupid.</p>
<p>Maybe the teacher can't do the problems w/o one =/</p>
<p>I brought my 92+ to campus (had an 89, but it died), and my first calc course doesn't allow any calculators on the tests. Go figure.</p>
<p>I find the 89 to be essential even though its not used on the tests. The reason is that you can do calculus on the 89, so when you're doing homework, you can use your calculator to check your solutions.</p>
