<p>Are there any classes that we need Ti 89's for, and if so, which classes?</p>
<p>maybe statistics. a lot of science classes actually disallow them, like physics and chem, they only allow simple calculators.</p>
<p>ti 89 is pretty useful though, not as useful as matlab or mathematica though</p>
<p>If you have one, bring it. If you don’t you don’t NEED to buy one. </p>
<p>If you’re in Engineering/Physics/math, there are problems in problem sets which are “impossible” to solve without graphing calculators. You could always just borrow from a friend or something.
If you’re MechE, there was one class (matprops and selection of materials) where if you had graphing calcs, you could spend 20min less solving the problem ON AN EXAM (that one was really unfair lol). Most classes don’t allow graphing/programmable calcs on exams.</p>
<p>Besides this, I have never heard of anyone complaining that they MUST dish out the money for a graphing calc for any class.</p>
<p>Matlab is useful but without prior knowledge, it will be hard to navigate. it’s much faster to plot equations on a graphing calc too imo</p>
<p>Just do it in your head.</p>
<p>I’m in ECE/CS and I don’t own a graphing calculator. I’ve never had any problems. If I really needed to solve something that I couldn’t do on my scientific, I just plugged it into Wolfram Alpha. Don’t waste your money or get into the habit of using a graphing calculator as a crutch.</p>
<p>i disagree with Feral. I have taken all my required math courses as an engineer including upper level statistics and I have barely needed my ti 84</p>
<p>well i have never taken statistics, i just remember statistics in high school was calculator heavy. otherwise, what is there to disagree with me about</p>
<p>you gave a bunch of examples of where ti 89s arent useful or even allowed and your “maybe” example wasn’t useful either and you conclude by saying they are “pretty useful”</p>
