Well I needed a new calculator so I bought one.

[LordMorpheus]

Yeah, in a world of MATLAB I don't see the point (outside of schools) in a graphing calculator.

A calculator fits in your pocket ;^)

OH! I love this game! "Which of these doesn't belong?" Hmm....

Maybe she was a 48G?

You can pry my TI-83+ from my cold dead hands.

Great, I need one. Will you ship it for free? :awe:

 

[Fritzo]

LAME

You're lame! Mine's in 3D. Yours looks like something that ran on Windows 95

I don't think you'll have any worries

TI's are OK, but RPN does the trick for me. My daughter uses a '83 I believe.

 

[Engineer]

Fuck you elitist RPN people. Why can't you do it the way regular people with their regular calculators do it?

RPN is the regular way. You are so full of fail.

Great, I need one. Will you ship it for free? :awe:

Maybe I should ship you a RPN calculator just to piss you off!:twisted:

 

[Demo24]

It stands for "reverse polish notation" and it is a different method of inserting data into calculators. Rather than typing A * B = you would type A B * =. It becomes more useful with larger expressions as it ensures that operators are performed in the correct order. For example if you have

A B C - *

The equivalent for a non RPN calculator would be

A * (B - C)

I see, that looks sort of confusing. Thankfully I'm not a math major so I'll just dock this away in memory. :awe:

Not confusing. RPN works on the stack method (at least on HP calculators). You put A, B and C on the stack. When you hit the - key, it takes the last item on the stack and subtracts that from the item above it on the stack. It then places the answer on the stack. When you hit the * key, it takes the last item on the stack (the answer from the previous operation in that case) and multiplies it by the item above it (A in this case) and then places the resulting answer on stack.

A
B
C
-

new stack:
A
(B-C) (answer)
*
new stack:
A*(B-C) (answer)

I was going to do this one

But it isn't so apparent that it comes from matlab.

Always was a fan of RPN so I bought this:

Should be here Tuesday.

If I had the energy I would post some cookies for you.

I'll have to post the next time I have a BM.

 

[MagnusTheBrewer]

This is the way we did it and that's the way we liked it.

 

[Minjin]

why
MathWorks MATLAB of Natick, MA
instead of
Wolfram Research Mathematica of Champaign, IL
?

I suspect Mathematica is the more powerful between them

They have different tool kits and certain things are easier on one than the other. It just depends on what you are using it for most often. For instance, Matlab tends to be used by EEs.

 

[Sphexi]

Wow, didn't know that HP still made calculators. Awesome!

Still have my 48SX bought during college (around end of 1991 or start of 92). Bought it from Service Merchandise (now closed down).

Total side note, but wasn't Service Merchandise the shit? You'd walk around and pick something, and it'd shoot out on a conveyor belt form the mystical back room. Awesome place.

Our local store was Best, but it was the same concept. It was also the only place locally you could get an HP calc at a decent price. I left the job a couple times to buy a new calc when mine broke. The time wasted leaving the job was far outweighed by the usefulness of the calculator, and my programs. It was quicker to leave, than stay and do everything manually.

I <3 my ti-89 titanium.

Hell yeah. I'd always hear those rollers going with peoples stuff coming out. I bought my TI86 there ~13 years ago. Heh I got a 89 a few years later for less than the 86. The last Service Merchandise here closed a couple years ago.

TI's are OK, but RPN does the trick for me. My daughter uses a '83 I believe.

You see '83s all over the place partially because professors know exactly what they are and aren't capable of (i.e. indefinite integrals)

10 years ago I passed calc 1 without actually learning any calculus because the professor let me use my TI-89 in class. I got all the answers right on the test but lost a lot of points for not showing work.

Now I'm taking math classes again and am actually interested in learning it. Funny what time does (I'm borrowing my brother's 83 btw)

TI-89 son... probably more responsible for my engineering degree than i am.
