OTerryA Posted November 21, 2007 Posted November 21, 2007 The TI-89 Titanium is still a "best in its class" and probably the most capable calculator you will be able to bring in to SATs or in many cases for tests also. It is a bit cumberson to use and the user manual is the epitome of user manuals everywhere (it sucks big time) but its capabilities are great. If you want to improve on any in the library of the many built-in functions, you can write your own.
kimchee918 Posted December 27, 2007 Posted December 27, 2007 Don't buy the Ti-89, it'll take you at least a week to figure out the calculator. You'll actually have to read the manual.... a lot
DJBruce Posted June 28, 2008 Posted June 28, 2008 It all depends on what the instructor lets you use. I'm only in high school and so am not into anything beyond AP Calculus and Statistics but I know we are only allowed to use a 84 or 83. I personal use a TI-84 Silver and like it. But I would suggest you use the same calculator for homework as on the exams. I know our teacher made use you the class set of 83 and I was not happy. It took me twice as long because some amazing person deleted the programs I needed and the piece wouldn't graph more than one equation at a time.
Miri Posted June 28, 2008 Posted June 28, 2008 Don't buy the Ti-89, it'll take you at least a week to figure out the calculator. You'll actually have to read the manual.... a lot Oh really? I was using it efficiently from day one. It's really not that hard. I have a TI-89 Titanium and a TI-84 Silver, the latter only because I was not permitted to use it in Pre-Calculus class several years ago. if permitted, as many have said, 89T is the best of its class, and that calculator has gotten me through so many AP and SAT tests you wouldn't imagine.
YT2095 Posted June 28, 2008 Posted June 28, 2008 I use the Sharp EL 9600 here: http://sharp-world.com/sc/excite/calculator/text/graphing.htm I like the touch-screen option, it saves having to type in a load of stuff again or using arrow keys when you only want to change one thing.
rpdwpb Posted January 25, 2009 Posted January 25, 2009 The person asked what is the best Scientific calculator, and not the best graphing calculator. All of you that said to go get a Ti-89 are idiots. First of all there is nothing this calculator will do that an $8 calculator will not do in HIS classes. Second he would NOT be ALLOWED to use it, my past 7 math teachers have all banned symbolic calculators from their exams (half of them will not even let us use ANY graphing calcs). Third there are no quick routes to learning math, either take the time to learn all the rules with an $8 calculator or you will not know why you are having trouble dividing by zero with your $500 super-computer talking calculator.
insane_alien Posted January 25, 2009 Posted January 25, 2009 graphing calculators are used in scientific contexts all the time. i use one. and you are allowed to use them. they just have to be checked for stored information upon entering an exam. they are extremely useful tools. and you couldn't use one if you didn't know mathematical rules.
SH3RL0CK Posted January 26, 2009 Posted January 26, 2009 Why not get a computer laptop and install some kind math program on it?
DJBruce Posted January 27, 2009 Posted January 27, 2009 Although math programs such as MathLab and Mathmatica are very useful having to use a lab top and such a program would be highly inefficient when doing test or quizzes. Also because of the ability to store information so easily it would make cheating incredible easy.
Baby Astronaut Posted January 27, 2009 Posted January 27, 2009 Instead of using a computer program on a laptop, why not use a phone browser? It's small and then you can hit a free online scientific calculator like http://www.ecalc.com
Petanquell Posted January 27, 2009 Posted January 27, 2009 Well, I hate people doing this but it's well known trick: 1) go to the shop 2) buy the most expensive calculator 3) do an exam 4) complain and return your calculator to the shop Pq
the tree Posted February 4, 2009 Posted February 4, 2009 Instead of using a computer program on a laptop, why not use a phone browser? It's small and then you can hit a free online scientific calculator like http://www.ecalc.com The calculator on my phone can do that. Anyway, I somehow imagine that taking my phone into an exam hall wouldn't go down well. I use a Casio fx-83ES which is the same calculator that practically everyone in the UK uses. It says on the packaging that it's recommended for GCSE and A-Level which means that well meaning parents get it for their 11 year olds who get confused when they accidentally put it into stats or table mode and can't get it out. It doesn't do symbolic algebra or graphics, which is why it is allowed in high-school exams, but it does have a good multi line display. I've never needed anything more complicated, except for occasions that justified getting out my laptop.
ed84c Posted March 30, 2009 Posted March 30, 2009 I swore by graphical calcs all through high school and college (graphing is a great method for checking if answers are reasonable.) Unfortunately at uni they only allow 3 calculators (none graphical), but the best of these is definately; Casio FX 991 ES. Can do matrices, complex arithmetic, numerical integration and solve sim eq. and quadratics.... These functions are a great help if you are one of those people (like me) who in exams throw away 20% of their marks from doing a "2+2=5"....
the tree Posted March 30, 2009 Posted March 30, 2009 Sounds snazzy, apparently I'm only permitted an 83 or 85. I guess that shows it's always a good idea to be aware of the policies.
ed84c Posted March 30, 2009 Posted March 30, 2009 Another good idea is to read through the manual thoroughly to work out what your chosen calculator is actually do and practice how to do it. Boring, and sounds obvious, but the number of times I've browsed a calculators functions weeks after the exam only to realise, "Damn! I didn't realise my calculator could do that automatically.."

You should check with your university (couse syllabus if you have access) before you purchase a calculator. Once you find out which types you can't use (more often than not you can only use what they tell you). (i recommend Casio991 for physics; usually you don't get to use calculators on math tests)
David_C Posted January 22, 2011 Posted January 22, 2011 Thanks for all this - I am starting an OU (in the UK) course revisiting maths after 30 years and never owned a calculator then - just a slide rule that was about (in real terms) 30 times the cost of the Ti89! and I was completely confused as to what to buy
khaled Posted January 23, 2011 Posted January 23, 2011 I love my Casio Calc that have the Natural-View, it shows equations like if they're written in the Notebook, standard Calc shows: [imath]c = a/b[/imath] natural-view Calc shows: [imath]c = \frac{a}{b}[/imath]
altonclark2775 Posted April 30, 2011 Posted April 30, 2011 are there restrictions in calculators in colleges? i think there should be limitations for students to not be really dependent on calculators and learn the concepts of formulas. thanks for this forum. i've been getting a lot of information from here. very nice.

DrRocket Posted May 4, 2011 Posted May 4, 2011 (edited) are there restrictions in calculators in colleges? i think there should be limitations for students to not be really dependent on calculators and learn the concepts of formulas. Alton A. Clark Licensed clinical social worker I was always perfectly willing to let students do 2 x 3 on their calculators. It did not seem to give them much advantage over the students who could do it in their heads. I personally favor HP calculators and RPN notation. Mine is an HP 48, and if I were buying one now I would probably opt for the HP 58. But any good calculator should suffice if you learn to use it. Once upon a time back in the near dark ages (1970 or so) a young physics prof bought an HP 35 calculator for about $400 (that is 1970 $). He figured that he could then sell his Pickett slide rule to some lesser light, someone perhaps not quite such a star clearly representing the future of physics. So he put a for sale notice on the departmental bulletin board. Along came a much older fellow who figured he might be able to get by with the rather nice Pickett slide rule, so he bought it. That older gentleman, that "lesser light", was Eugene wigner. Edited May 4, 2011 by DrRocket
Schrödinger's hat Posted May 12, 2011 Posted May 12, 2011 Check what your college allows in exams, many have restrictions on features or allowable models. Out of the models that my university allowed, I was quite enamored of the Ti-34. or you could do it the hardcore way with a pencil and paper. i passed an exam that way. damn batteries. a TI-83+ should be able to do everything you need. mine does. then again i'm not in a pure maths course or anything i only need to know some engineering maths. Puts me in mind of my second year SR exam. I'd left my bag/calculator in another building but still had time to go and get it if I ran. I asked my lecturer (who knew me quite well and had taught me before): "Do I need a calculator for this exam?" He responded: "Do you need a calculator for this exam.....hm....no." Turns out, he knew that I knew an algorithm for calculating square roots and how to calculate trig functions for arbitrary angles by hand :/
Guest ashish45 Posted October 14, 2011 Posted October 14, 2011 I suggest you best Scientific Notation Calculator.This calculator solve all your problems. I am sure this Scientific Notation Calculator is very helpful for all of you.
