jerohm Posted January 14, 2004 Share Posted January 14, 2004 Actually I think that is reverse polish ... and it makes a lot more sense once you understand how useful it is to operate on a stack ! Quote Link to comment Share on other sites More sharing options...
JohnA Posted January 14, 2004 Share Posted January 14, 2004 This is what I use every day. I have two of them. The second was for parts, but it works as well as the original. I got it as a graduation present to take to engineering school. Quote Link to comment Share on other sites More sharing options...

tpg Posted January 14, 2004 Share Posted January 14, 2004 I am in AP Calculus in high school... (equivalent to Calc I in college, I think)... and I have a TI-86... but it really doesn't see much if any use these days. I do most of the math in my head (which is the best way to do it...)

I only paid about $2 for it and that was some 5 years ago. Handy little thing for balancing the check book or to take shopping if I need to run some numbers (just how much is all that going to cost me once I figure in taxes and such). As for what I need the fancier TI-68 calculator for? Well, I do alot of base conversions (going from Decimal to Hex to Binary) as well as having to perform math within the Hexadecimal system. A royal pain to do in the head or on paper, especially when dealing with 32-bit values. Quote Link to comment Share on other sites More sharing options...

Lewis The TI is WAAY faster than a PC for most of my engineering calculations, unless I have to do them over and over. I can calculate runoff for one basin in about the time it takes to get Excel running and the equations written. It was $225 in 1975. That was almost a week's take home pay when I went to work in 1979. Quote Link to comment Share on other sites More sharing options...

Not everyone has the same need in a calculator... and it is useless to have one which has 20E6 functions that you'll never use. In my case, matrix functions are still useful but I have to admit not using the integration features since university (thank god for that... ). PC connectivity is one thing I'd like having as creating a custom program must be so much easier with a real keyboard... Later... Rob PS: thanks for clearing up the Reverse Polish Notation... would have never guessed that's what RPN stood for... Quote Link to comment Share on other sites More sharing options...
Sublime40 Posted January 15, 2004 Share Posted January 15, 2004 HP 48Gx with TDS COGO card. When I was doing land surveying for a living, had to have one of these to perform field calculations. I'm pretty sure you could rule the world if you knew how to use all the functions. Quote Link to comment Share on other sites More sharing options...

Klipsch Employees Trey Cannon Posted January 15, 2004 Klipsch Employees Share Posted January 15, 2004 Some time ago, PWK got a new calculator. In the book that came with it were the instructions not to use the unit in a temp. above "X"deg.'s Paul was found one day with the heater on in his office and striped down to his boxers testing the function of the calculator at the temp that was stated in the book. He found how to make the unit work under this temp and sent that info to TI so they could "...get it right next time..." TI sent him 2 of the updated models....

m00n Posted January 15, 2004 Share Posted January 15, 2004 LOL... Just thinking about that and looking at a pic of him, he sure looked like a ornery ol fart. Quote Link to comment Share on other sites More sharing options...
tpg Posted January 15, 2004 Share Posted January 15, 2004 PWK was quite a funny guy. lol Sounds like something I'd do out of boredom. hehe Quote Link to comment Share on other sites More sharing options...
WMcD Posted January 15, 2004 Share Posted January 15, 2004 I must take some issue with mOOn. I met PWK shortly before he passed away. His faculties were failing. Old fart? No. He'd probably say he was, in the underlying personality, the same in his youth. Like in many situations, we are only able to appreciate the intellect and wit of geniuses through their writings. I read one of his articles, published in 1957, today. Very forthright, full of first hand experience and . . . charming in its truth. - - - - On the original subject. I'm quite convinced that spread sheets are the way to go for calculations. Gil Quote Link to comment Share on other sites More sharing options...

gtDark Posted January 16, 2004 Share Posted January 16, 2004 To John Albright and formica: my PC running Matlab can perform matrix math a lot faster than my TI-89, maybe that's just me though. Also, regarding PC connectivity, Texas Instruments website has programs/plug-in's available for download and transfer to your calculator...I've done this in the past. John, are you a C(ivil)E?

dougdrake Posted January 16, 2004 Share Posted January 16, 2004 John's one of the most civil E's I've come across. In the years I've been around this forum, I think I only saw him get his dander up once, and it was deserved!! dd Quote Link to comment Share on other sites More sharing options...
