<p>So I have always used my ti-89 wherever a graphing calculator was required. I recently looked at the math department website at wustl and saw that that the ti-89 is not allowed on "most assessments"? </p>
<p>Has this not been updated recently, or is that actually the case??</p>
<p>I would purchase a TI-30XIIs and get familiar with it, just so you have something for the classes that won’t allow graphing calculators. There are plenty of classes that’ll allow TI-89’s as well, but you’ll need to be comfortable on a non-graphing calculator. </p>
<p>If you’re wondering if you should step down to a Ti-83 or Ti-84, though, I wouldn’t… at least since you already have the Ti89. In my experience the Ti89 is pretty much allowed any place there’s no rule against graphing calculators.</p>
<p>If I remember correctly…you can use graphing calculators on assignments and in class and stuff…but for tests they won’t let you use them (you have to use a regular scientific calculator). It will depend on the class…I seem to remember being allowed to use a graphic calc for my statistics class because you would need to in order to do anything…but for like calculus class I think not… </p>
<p>It’s not really a big deal… I don’t remember if this was a prohibition on any specific graphing calc or just a prohibition on graphic calculators in general…<em>shrugs</em></p>
<p>I’d keep the one you have until someone tells you specifically not to use it, then borrow someones TI-83…</p>
<p>ah ok. im just worried because i dont know how to use any graphing calculator besides the ti-89. not too worried about scientific-calculator or non-calculator assessments</p>
<p>this is what i was talking about btw:
"However, some higher-end calculators contain a computer algebra system (CAS) that allows them to perform symbolic manipulations-- for example, to simplify 2<em>(2</em>x+1)^2 - 3<em>(3</em>x-2)^3 . Calculators containing a CAS (for example, the TI-89, TI-92/TI-92 Plus, Casio FX2, HP-48 and HP-49) are usually not allowed at math quizzes and exams. "</p>

<p>It depends on the teacher.
What I’ve had:
Calc II- scientific only
Calc III - none at all
DiffEQ - anything, 89 included
EnMath - no trig functions (ie add subtract only), but EnMath is not in the math department</p>
