TI-89 Calculator

[Metal4130]

Does anyone have one that they aren't using and would like to sell? PM me.

[Matt_E]

College?

Great for Calc, but for Engineering, the HP48 rules.
I'm a HP48 guy.

[The Penguin]

are you using it for engineering?

[Matt_E]

Talking to me?


Yes, I am using the 48 for engineering. (Electrical)

[The Penguin]

well no, I meant Metal4130 - but whatever.

are you going to be taking the PE exam?

[Matt_E]

Not for a long while. Still working on the BS. :crazy:

[The Penguin]

ah - don't get too dependant on that calculator. If/when you decide to take the exam - there is currently a list of 8 specifically approved calculators that can be used on the PE exam.

for HP, you can use a HP30 or HP 30 Solar I believe. there's a few TI's and a few Sharps that are approved.

basically:
if it has a big screen - no good.

if it is programmable - no good.

I saw a guy get kicked out of the exam for having a simple regular desk calculator in addition to an approved calculator.

they are great, but you can't be too dependant on them...at least on exam day :biggrin:

I got mine off of fleabay for $80 bucks I thought it was a steal. When I got the calculator everything was fine but the serial number on the back was scratched out so I think it was stolen, nevertheless a nice calculator for near half the price. Still trying to figure out its capabilities but whenever I am unsure on something I always go back to the trusty TI83.

[Metal4130]

Yes, I am using it for engineering. P.E. is a long way away for me. It is just nice to work out derivatives on the calculator to see the final answer. I still have to show all work.

[The Penguin]

what kind of engineering?

That is such bs. They'll let you bring in any material you want but only certain calculators. Do they actually think engineers work on a day to day basis with out one of these?!? I'm gearing up for the PE in April and this has me more worried than just about anything. Grrrrrrr

:banghead:

Oh, and I'm a civil...

[Matt_E]

Oh, and I'm a civil

Building targets. :biggthumpup:

[Metal4130]

Mechanical for me.

[X2 RAGS]

im all mechanical,

btw i have a couple of these cal's let me know

the problem with calculators is you can program them with all sorts of neat stuff that will do the work for you...some calculators have the ability to communicate with others (at least that's my understanding)

what discipline test are you taking? I did the water resources. The test is not that bad if you prepare for it. I started about a month before and worked every sample problem I could find.

then re-wrote them again neatly and bound them to take into the exam.

Get you Civil Engr. Reference Manual (by Lindeburg) and become very familiar with it. The "7 minute solution" series of books is excellent review material and very typical of the types of Q's you will find on the test.

[tor*p*do]

I am a chemical engineer
Got my PE in Environmental, which is what I do for a living
Exam was a cakewalk IMHO :Banane01:

[Dustin Mustangs]

I'm looking at either water resources or transportation. I work in both and they both also came real easy to me in school. I guess I need to make up my mind here pretty quick. I didn't even crack a book for the FE (and passed), but this one has me a little more worried. I'll deff check out those books you mentioned...

[Dustin Mustangs]

Building targets. :biggthumpup:

BIG ones, lol. That's one of my favorite engineering jokes.

[dbrutherford]

I did the same as Dustin on the FE, never studied, never tried too hard. I guessed on the first exam for probably half of it! I had to take a leak wanted done with the test ASAP. Then in the afternoon, I took Industrial, I was already disinterested and guessed a twice as much as the morning test. I still passed :). "I remember studying this but.. pick "B" it is the new "C". The 4.0 girl who always got A's in my classes failed the FE twice! my idiot buddy with a 2.0 GPA passed it the first time. Go figure.


I never used an HP but I loved my TI 89. You can download all kinds of games and software from TI for it. I would put all the formulas in it for exams. Call it cheating but I feel it is ridiculus that a professor won't give you a formula sheet for a test! There is software on TI's site you can put on your PC and type the stuff in the PC then transfer to the calculator.

Being an avid, TI 89 user, I did have a bit of trouble on the FE with the TI30X pile I was using. I just wasn't familiar using it and i bought it the day before the exam. I do recommend you get acquainted with the FE or PE legal calculator months before you take the exam.

I sugguest a TI 89 Titanium because it has more memory and features then the regular 89.

If you need math help look to MathCAD. It is pretty simple to use and will help you a ton with calculus. I never used it that much for my regular classes. You can buy it cheap from a place called Jopurney Ed or Academic Software. Google them.

If you need a huge help... look for the instructor's solution manuals on Half.com Saved me a lot of work. Cost was 5-25 bucks. Just don't tell your friends, the professor will catch on when everyone has the exact answer as the manual. A lot of times there are mistakes in the manuals too!!! Don't rely on them 100%. I did sometimes and now I wish I hadn't. Then again I am not building airplanes or bombs and I only use say 5% of what I learned in college and I got 2 degrees...

My degrees are both BS in whats listed down below.

[boggs]

one of my EE professors was telling me that one of his students once took everything inside a ti 89 and put it in a ti 36 or whatever is allowed.

[dbrutherford]

I don't see how that is possible, TI 89 to TI36. Maybe an EE/CpE kid could do it? Well you could cheat the old fashion way and have little slips of paper stuck inside the cover of the calculator behind those instructons they have.

Then again I think they make you take out that instruction sheet and they walk around looking at your calculator when I took the FE.

My friend would just write the formulas between the keys on the calculator he had. He was real old fashioned... he would just look over your shoulder sitting beside you during an exam. I used to get pissed after exams because he was like yeah I looked right off your page... Here I am digging through my calculator for formulas which is cheating... but then he is straight up copying off me!
