<p>Hi, I am currently a senior in high school. I', in ap calc this year, and was wondering if it would be a good idea to invest in a ti89. I am hoping to attend uf next fall, and major in either microbiology or some type of engineering if this helps.</p>
<p>Hi gator, my kids have ti89 calculators and they are in engineering and biology. I'm just a mom, though. We actually just replaced one... grrrr... that got 'lost'. If you are thinking about replacing a calculator (say, your ti83), I'd replace it with the ti89titanium. Can't hurt.</p>
<p>Personally, I would say no. At UF you cant use a calculator in calc 1, 2, or 3. Some differential equations classes use it, as well as some calc 3. If you decide on microbio then I would defiantly say no. You wont use it. A scientific is all you need. If you are engineering then you can buy it (but a 89 is not needed), but if you want you can get it. I know many who use an 83 in engineering.</p>
<p>Also microbio, from my knowledge only take up to calc 1 (and many take stats too). Biochem goes to calc 2.</p>
<p>If you have to take stat, I'd get an 84. I have an 89 (I'm in high school), and it's great for calc when we're allowed to use it, but it's slow on a lot of stat things. I find 84's to be very efficient when it comes to stat.</p>
<p>Get the 89. It helps for chemistry, especially when you want to type everything in.</p>
<p>I'm in calc2 now and my professor lets us use our TI89s on the test</p>
<p>I wish my calc teacher let us use 89's on our tests. I think he's afraid of them, though. Seriously.</p>
