<p>Im going into Bio major or bio molecular at CAS. Im just wondering do any Cornell classes restrict which graphing calc u use? (or, can you even use any graphing calc on exams?) I just bought TI89 Titanium and TI83 plus today and i'll get one of them refunded but im not sure which one i should keep. I know some colleges do not allow TI89 because its so powerful.</p>
<p>Generally, and it's not just Cornell, no calculators may be used in any calculus class. Not sure about others though as it largely depends on the nature of that particular class.</p>
<p>When I was at Cornell no calculators were allowed in my calc and physics courses because the profs wanted students to be able to solve all of the problems using their brains instead of a computer. I actually liked not using a calculator because I could focus on solving problems with nothing but letters, symbols, and simple numbers. I've since transfered to a different school and many of my exams require lots of number crunching and it is very easy to make a math mistake with a calculator.</p>
<p>Calculus without calculators make the tests tougher since they actually test your knowledge instead of whether you can punch in 129+345 into your calculator which everyone (except justinmeche apparently) can do.</p>
<p>My (high school) multivariable calc class uses TI-89s all the time. I think it's a good idea--you waste a lot less time on stupid number-crunching or basic calc derivatives/integrals that you wouldn't have to do in the real world... cause you'd have a TI-89. (I'm more engineering-oriented, I guess.) The other day I was really glad I had it because I didn't have to plug in a million functions of t for x and y functions of line integrals. Could I have done it? Sure. Would I have learned anything? No.</p>
