My professor today told the class(engineering statics) that we should invest in the ti89 or an equivelant. He claimed that the ti83 was good for middle school but not for University work.
However, I was forced to buy a ti83 because the math department at my school doesnt allow anything higher. When we studied statics in general physics it never seemed necessary to own a better calculator but Im not sure how much more detailed this course will be. Would you say it would be necessary to purchase a ti89 for the class(engineering statics)?

You should ask him specifically what he expects his students to use the calculator to do. Is he expecting you to compute integrals with the calculator, even if you don't know how to do them by hand? A welldesigned class honestly almost never demands the use of a calculator, though sometimes it can speed up boring computations.

No, you will never need a Ti89. What the hell would you need an 89 for in statics?

Engineering statics calculator
Well, my suggestion would be to know where you can get one quickly if you do find you need it, and then wait to see how the coursework goes. If you find you can get by with what you have, then great, no need to spend more money on another calculator. If it turns out you really DO need a better calculator, then you'll be ready to buy it as soon as you get into the material that requires it. That sucks that they're making you buy two different calculators. When I was in college, none of the engineering majors needed special calculators for their classes...it was more like your math department where they were discouraged in favor of learning how to actually work the problems rather than letting your calculator do all the work for you. You ought to know how to crunch numbers by hand if it really came down to it, but then I'm oldfashioned about things like that. So, I'd just take a waitandsee approach before shelling out more money for a calculator if you really don't need it (you may find that you can do the problems with the one you have, but not fast enough to get them done on time in an exam, in which case, you will not want to wait until the first exam to determine this).

I can honestly say that a graphing calculator is a tremendous asset for many kinds of engineering work. Often, just being able to visualize whatever problem you're working on will give you enough intuition to solve it properly.
The higherend calculators include computeralgebra systems, which can solve equations, compute integrals, etc. The problem is that most of them are pretty primitive, and cannot deal with truly difficult problems. The only integrals they can easily solve are the kind you could easily solve on paper, too. You're better off just using paper most of the time, unless there's just a ton of simple, annoying algebra to wade through.  Warren

A Ti83 is a graphing calculator that does linear algebra. The only thing a Ti89 does is solve integrals. You dont need a Ti89, period.
If you cant do it on an 83, use a table of integrals and learn to solve it in matlab.

Get a Ti83, and remember, Maple/Mathmatica are your friends, and one of them should be on your math and physics department's computers.

Its statics. You dont need a Ti89 for statics.
You could do statics on a calculator that has only the most basic functions.

Once I became a math major, I decided to go all out and buy a TI108: http://www.amazon.com/TexasInstrume...005950&sr=129

Personally, I've found a good calculator is invaluable for some engineering courses. The Pickett N4ES is particularly good for electrical engineering courses due to the dual base logarithmic scale (a lot of problems require base 10 logs). It also solves quadratic equations very quickly using a visual iterative process.
Pickett N4ES (Edit: Don't forget to move the parts using your cursor. This really works.) Of course, it doesn't help all that much in statistics, since it doesn't do sums. Then again, Microsoft Excel can do anything you want to do for statistics and most of what you want to do for any other course (provided you simplify the calculus problems by hand into something you can enter into Excel). Edit: Or, alternatively, you can buy a Picket N525ES that's specifically designed for statistics. Pickett N525ES Stat Rule
