<p>So yeah, there was a similar thread like this by a different person, but I don't know how to read old posts, and I can't remember what people were saying, so here I ask the question now.</p>
<p>Does having TI-89 (Titanium, dude) instead of TI-83 plus actually hurts something? I think it does the same thing TI-83 does, but this is the first time I use graphing calculator, so I know nothing. </p>
<p>Anybody who answered the question, you may go to a gorgeous trip to Hawaii for a week (of course, with your money) :)</p>
<p>The TI-89 can perform a lot more functions than the TI-83 can (symbolic manipulation and such). Finding evil indefinite integrals with the 89 is definitely nice.
Disadvantages of the 89 are that you can't use it on the ACT, and it's often banned at math competitions (if you participate in those).</p>
<p>I use it more than I use a pencil. Don't get me wrong... I have both a TI-89 Titanium, and a TI-83. </p>
<p>When I'm learning a new subject, I use the 83, since it can't do as much. But once I have it all down, I take out the Titanium for silly things such as homework as tests (unless I have to show work, but even still I make sure I'm right with the 89). </p>
<p>Honestly, I find it to be a godsend. I love it and I don't know why I didn't buy it earlier, but I'm glad I didn't cause then I woulda been ****ed off when the titanium edition came out. Today I was doing limits in class, they're about to enter derivatives yet I'm about to start chapter 6, and I asked my teacher if there was a way I could put in a limit such as: lim(x->-3+)... he replied no, and then tonight I stumbled upon it and now I <3 it a lot more ^_^. </p>
<p>After using the 89, I hate going back to the horrible screen quality of the 83, not to mention the 89 has all the 'pretty' font. As for competitions... my team doesn't use calculators lol, my romanian teacher insist, "If you were in romania, you'd be doing integrals and such in your head"... w/e</p>
<p>BTW, I often find my friends asking me/trying to steal my TI-89 tit. because it's just faster and has more memory than the 83. The feature I <3 the most is probably between the "exact" setting (great for math 2C) and then all lim, zero, expansion, and solver() (great for physics).</p>
<p>As you can see I <3 my TI-89 tit. and always carrying it around with me. I would recommend it to anyone, as long as its in their budget (although I think it's worth spending a bit extra on)</p>
<p>Make sure you can actually solve all the things the Titanium can solve on your own though. There's something really pathetic about seeing a math "genius" reduced to a bumbling idiot because his calculator was taken away. Sure, I'm pretty dependent on my TI 83 (which I lost... um... last Thursday), but I do know what I'm doing. Then again, I have a friend who just moved to a Venezuelan school where she isn't allowed to use any calculator whatsoever.</p>
<p>Off topic, but can you solve one sided limits with the TI-89 Titanium? I looooovvveee my calculator but my teacher is completely ignorant with it... he has no clue what the capabilites are and what they can be used for. It's probably to my advantage because if he did know he wouldn't let us use it(it big on hand solving EVERYTHING)</p>
<p>I am also the proud owner of a TI-89 calculator, and i ADORE it! I had no idea there was this new TI-89 Titanium. My reaction in one word: sexy! Calculators definitely get me excited.</p>
<p>Me too!
For Calculus and Stats, it’s a must-have! Anything below that, though, it’s just the same as TI-83/84, but you need to press more buttons to do what you wanna do.</p>
<p>TI calculators are overpriced. You can get a more powerful HP for less money. TI cornered the education market and used their influence with educators to increase student demand.</p>
<p>With that said, the TI-83/84 lines are fairly uniquely idiot-proof.</p>
<p>TI 89 solves calculus problems for you. It’s awesome. I wish I had it, but I already paid $100+ for a TI-84 and I’m not going to buy a new calculator just for the AP Calc exam.</p>
<p>The 89 is awesome, but I’m too used to the 84 that it takes me longer to do calculations/graphing with the 89 than with the 84. So, I only do calculus (integral, derivative, etc.) on the 89 and everything else (Stats) on the 84.</p>
