<p>If one was planning to take the Math 20 Calc series followed by the Econometrics series, which calculator should one buy? TI-84 or the TI-89? Is the TI-89 allowed for use in class and EXAMS in all Calculus classes? I guess what I am asking is what is the attitude of professors towards allowing the use of TI-89 in the classes and for exams.</p>
<p>THANKS IN ADVANCE.</p>
<p>no calculator is allowed for math period. 20a-f. not sure about 10.</p>
<p>Like the above poster noted, no graphing calculator is allowed in the 20 series (at least at SD/SC). There is no specific problem with professors and the 89, however. It is just seen as another graphing calculator.</p>
<p>Wow, I am really surprised. I was about to order the TI-89. Here is what TI says on its website:</p>
<p>“The TI-89 Titanium’s advanced functionality and 3-D graphing make problem-solving for AP<em>, advanced mathematics, and engineering courses infinitely easier. It’s the most powerful TI graphing calculator allowed for use on the AP</em> Calculus, AP Statistics, AP Physics, AP Chemistry, PSAT/NMSQT**, SAT® I , SAT II, and Math IC & IIC exams.”</p>
<p>I figured that if it was allowed for these purposes, perhaps it would be allowed for UCSD Math 20 Series. </p>
<p>So, what do the students in these classes use? what is allowed? THANKS.</p>
<p>Students use their brains, not calculators.</p>
<p>Math classes teach math, not arithmetic.</p>
<p>Just use a netbook and wolfram alpha.</p>
<p>Don’t get a calculator; get a calcu-now.</p>
<p>I hope one of these sentences is marginally helpful.</p>
<p>(I actually had a professor who let us use calculators, I believe, but he no longer teaches at UCSD.)</p>
<p>Everyone is right, I have not had a math class where a calculator is allowed. </p>
<p>Even when I do my homework, there really is no need for one. And I have taken a good amount of math courses.</p>
<p>Is there a point of even taking my calculator to school?</p>
<p>Speaking of Math, do you think Math10A will fill up quickly for freshmen between 25th-28th of August? I looked at Fall 2008’s Math10A Schedule of Classes and on average there were about 1-2 extra seats. =/ Just worried.</p>
<p>toreypines - How often did you need to use a calculator in CalcAB? I can’t think of much… the teacher can easily make problems that do not require number crunching.</p>
<p>Slorg, can you elaborate on your comment: Just use a netbook and wolfram alpha.
I have a netbook but have not used it yet and I don’t know what wolfram alpha is. Yes, I will research it but would still like to hear more.
Thanks</p>
<p>Do you need (or required) calculators for Physics or O-chem?</p>
<p>Thanks</p>

<p>[Wolfram</a> Alpha](<a href=“http://www.wolframalpha.com/]Wolfram”>http://www.wolframalpha.com/) will compute anything for you.</p>
<p>(This helps with homework; computers are obviously not allowed for tests. If the chances of a professor letting you use a calculator are infinitely small, then the chances of a professor letting you use a netbook are uncountably infinitely small.)</p>
<p>well the 10 series accepts graphing & non-graphing calculators… it’s relaly weird</p>
<p>but no for 20 series</p>
<p>Do we need a calculator for Physics or Organic Chem?</p>
<p>You do stoichiometry-type problems in physics and ochem, so I’d say yes if you want exact answers, although you can usually guesstimate pretty close if you try.</p>
