<p>I will be majoring in chemical engineer and minoring in math this coming fall. Should I get the ti 89 titanium or the ti 89? Is the extra feature for the titanium worth let's say $20? Thanks.</p>
<p>I wouldn't buy any expensive calculator. I haven't had a single college math class (I've done Calc 1-3, DiffEq, Engineering Math, and Linear Algebra) that will let you use a calculator on a test, let alone a graphing calculator.</p>
<p>My engineering classes have been split 50/50 with allowing scientific versus graphing calculator. I don't even use my graphing calculator when allowed because it would have given me no advantage.</p>
<p>I'd save your money and buy one online if it turns out you want/need one. A good scientific calculator is really necessary for engineering. (I've heard the same from students at other schools too)</p>
<p>I have had a Ti 83 but I lost it. It was pretty helpful when solving linear algebra questions. Since I need a new calculator for college anyways, I might just spend some more money to buy a ti 89. I also heard titanium is better to solve stats, i m not sure if it is true. hmm</p>
<p>well I've been using a TI-89 Titanium for over 2 years now, and it has been extremely useful, especially if you downloaded some applications like calc. tools that will help you a lot and save your time. Being able to draw a graph of a function may be very helpful in understanding things, I strongly recommend that you get one, it's worth the cash. Never care about the money when it's spent on education.</p>
<p>it will give you the edge if you know how to use it to your advantage</p>
<p>you will get to know how to use it eventually don't worry about that</p>
<p>The differences, according to Wikipedia:

The touted advantages of the TI-89 [Titanium] include four times the available flash memory (with over three times as much available to the user). The TI-89 Titanium is essentially a Voyage 200, except it doesn't have an integrated keyboard. The TI-89 Titanium also has a mini-USB port, for connectivity to other TI-89 Titanium calculators, or to a computer (to store programs or update the operating system). The TI-89 Titanium also features some pre-loaded applications, such as "CellSheet", a spreadsheet program also offered with other TI calculators. The Titanium has a slightly updated CAS, which adds a few more mathematical functions, most notably implicit differentiation. The Titanium also has a slightly differing case design from that of the TI-89 (the Titanium's case design is similar to that of the TI-84 Plus)

<p>It's up for you to decide. It depends if you think you need these features or not.</p>
<p>I will probably just get a regular ti 89, since a lot of the programs can be downloaded later. Thanks for all the help.</p>
<p>The new TI Nspire series will be coming out mid august so you might want to wait on purchasing a new calculator. If anything, the prices for the TI-89 will drop significantly come release time</p>
<p>is the nspire going to be able to be used on the SATs and/or AP Calc?</p>
<p>no qwerty, so it should be able to.</p>
<p>sweet, it is.</p>
<p>i don't know if i want to get the CAS, or the normal one which as 84 support.</p>
<p>Air Jordans won't make you a good basketball player, if you catch my drift.</p>
<p>get the CAS edition especially for an engineering major</p>
<p>I have had a TI-89 for years and I feel no particular sense of envy towards those you have 89 Titaniums. I just don't see any particularly vital advantage to having a 89T over an 89.</p>
<p>And 89s are very useful in college. You'll be taking more than just math classes. Your 89 will be of great help in your chemistry, physics, and engineering classes.</p>
<p>I finally got a ti 89 titanium on ebay for less than $80. It is more or less $10 more than the regular ti 89, so it's not a big deal.</p>
<p>You don't have to buy a data cable to the Titanium. Some schools actually let you use graphing calculators on tests, especially in upper-division engineering classes where a calculator won't help you at all. It's still useful for doing lengthy homework problems. Here, I'll teach you the function that you'll be using the most:</p>
<p>solve(equation, variable)</p>
<p>for example:</p>
<p>solve(x^2 = 9, x)</p>
<p>Derivatives and integrals too. You can d/l programs for differential eqs and Laplace transforms.</p>
<p>Great. Thanks!</p>
