<p>Well I have a Ti-83 which i got for free from my school.</p>
<p>I am an engineering student and have never taken calculas.</p>
<p>would you say the ti-89 is needed as a engineering student or would i be fine with the ti-83</p>
<p>I have a TI-83 Plus, and I've only graphed two equations. I'm also an English student, so...yeah. I don't really know.</p>
<p>It's more than enough for calculus and should be fine for intro engineering stuff (but I have no experience with engineering, only calc and science, so this is just a guess), be sure to check the course descriptions. You might eventually need the upgrade but it's better to wait as the new models get memory upgrades etc periodically.</p>
<p>The TI-83 is definitely enough for calculus, but when you do get into more advanced engineering then you might need the TI-89. But I'd for now just have the 83.</p>
<p>i hate Math</p>
<p>Are you even allowed to use calculators in your calc class, I'm not all the way through calc 4. We have to know how to do everything out...</p>
<p>Yeah grab a ti89 off ebay for 50-60, don't waste money on the titanium. A ti89 is soo much more helpful for any kind of math, especially anything symbolic. Once you get used to the different interface, you won't understand how you could have liked a 83.</p>
<p>that's very true. the 83 just seems no better than a regular scientific calculuator once you get used to the 89.</p>
<p>I used the 83 in calc 1, but in calc 2 got the 89...you don't need it necessarily, but it is definitely nice to have because it does so much more stuff...solves equations, factors, etc. anyway, go to a few days of calc before you buy an 89...it may turn out you cant use one at all.</p>
<p>I haven't found a need to have an 89 (in engineering classes). It's a good workout for your brain to be able to solve derivatives and integrals of all sorts of crazy things without the aid of a calculator. There have been a few times I wished I had an 89 to solve a nasty problem, but I could almost always borrow one from a friend (I never ran into a problem on an exam that couldn't be worked out by hand)</p>
<p>I love my TI-89 (I even had to go out of my way to get the original rather than the titanium which just dont feel as solid than the tried and tested 83/89 case).</p>
<p>It is great but it is also much more complicated so if you dont think you will need it, dont bother.</p>
<p>Any of you 89 people know of a good tutorial on the web? I completely forgot that I got an 89 for Christmas last year, but only used it once!</p>
<p>I'm so used to the 83. The 89 seems so complicated!</p>
<p>whats wrong with the Titanium.</p>
<p>is it just a waste of Money.</p>
<p>At the moment, the Titanium is an all-new TI design complete with more memory than the older TI-89 as well as a faster processor. It's the same differences as those between the TI-83 Plus and the TI-84 Plus, etc. I have the Titanium and the layout of the keys does feel weird opposed to the old-style 83. But the sliding cover is definitely much more solid; so solid that I have trouble getting it open!</p>
<p>But if you can get a regular 89 for much cheaper than a Titanium, then I say go for that.</p>
<p>well you can Like get a used 89 for $60-79 on ebay</p>
<p>so I guess I will go with that.</p>
<p>so is thier an online manual for this calculator.</p>
<p>there should be a pdf on the ti education site! :)</p>
<p>lol il check that out thanks.</p>
<p>in my HS they actually had a whole semeter class based on the Ti-83, </p>
<p>I can only imagine with the 89.</p>
<p>the cover may be hard to get off of hte titanium (but it is really fricking hard to get off my normal 89...thats how they all are when they are brand new) but the actual case is not as sturdy as the black abs case shared with the 89 and 83/+, its walls are thinner and the buttons are a different style that is more prone to wearing out. The memory isnt a big deal unless you play a LOT of games on the calculator (I have had many on there at once without the Ti and rarely do educational programs take up much space). and the processor is downclocked on the titanium to keep it compatable with the original 89 so it hardly makes a difference.</p>
<p>hey where do u get the games for ur calc..i've got a ti-89 titanium</p>
