Total Posts: 97 | I have a friend who thinks that I'm a fool for having so many calculators. He argues that "all of your calculators will be pretty much useless once you are out of college". By this, he feels that "I won't ever use calculators in my job".
I disagree. I can't believe that there isn't someone out there who uses some form of a graphing calculator for work...........
Am I right? Is there anyone here who can think of a descent rebuttal to my friend's argument?
Thanks. :) |

-software engineers
-computer programmers
-mathematics teachers
-research scientists
-computer scientists
-economists
-accountants
-statisticians
to name a few. That should prove your friend wrong.

Total Posts: 97 | Well, I did think of math teachers, but do the others really, really use actual graphing calculators? Are you sure that they aren't all just using account-software of regular computers?
I apologize if it appears as though I'm making this rather difficult and absurd.....I'm honestly not trying to... :) |

Total Posts: 97 | Well, I sure hope so. I spent way too much money on these calculators! :)
Another question is: "Howe much more advanced (in mathematical capabilities) can these calculators really ever become?". I mean, think about it. Outside of adding more memory, a nicer screen, and perhaps a different case, is there really much more that TI can do to make these calculators more powerfull in the future?
Math does not really change. So, why would the calculator? |

Total Posts: 310 | I don't do a whole lot with my calcs that I couldn't do with a plain old scientific calc or even a four-function, but I do so very much prefer the graphing calc interface. I do still use the unit converters a lot, since most of the stuff I work with is given in standard units but when I do small scale trial mixes of stuff I'd rather work in metric.
Calculus stuff or actual graphing? Nope, don't do that. Though come to think of it, I never used either of those all that much in school either. Chem and metallurgy only occasionally get that deep into math. |

Edit | I recieved an email from a guy that builds cutting tools, he had some problems figuring out some equations with his 83... And I got it fixed of course. :D
Original Email:
Dear sir,
Hello and good day.
I have a question. Using the equation solver on the TI-83, I cannot figure out how to put the following in.
D * 3.141592654 / tan( H = L
D = outside diameter of cutting tool
H = helix of cutting tool
L = lead of cutting tool
The formula is used to convert tool helix to lead to manufacture cutting tools on a seven axis cnc tool and cutter grinder.
I am hoping to put this in my TI-83. I looked on line and I can put in addition, subtraction, multiplication and division.
The tan is causing me problems. Any help would be greatly appreciated.
Example = 0.750 * 3.141592654 / tan( 20 = 6.473591158
Thank you very much for your time and have a nice day.

Edit | He wasn't in degree/radian mode? I know a student that was in my trig class that completed a test perfectly, except for the fact that he was in degree mode and had to be in radian mode. He got every question wrong, but the teacher was nice enough to give him a passing grade. |

Oh and about that, I finally talked to him and he said I should forward him that list of questions I made. However, I lost it. What do you want on there now? Erm, maybe that should be in a different thread.

Total Posts: 310 | Yeah, I've helped a few people port over programs for use in their occupation. One of them had the original in an Excel spreadsheet, and I guess for taking the program on the go, a V200 is cheaper and smaller than carrying around a laptop PC. There's probably a lot of that around, people who use the calc only for a handful of programs all the time and having the graphing calc saves them from crunching the numbers longhand. |

Total Posts: 61 | in all reality, you really won't use them much. Keep in mind that the website is "education.ti.com", they are specifically designed for use in school. Afterwards in any serious field you will be using more powerful software on the comp, or just a basic 4 function or scientific calculator made for your profession (i.e accountants). But you could always sell them on ebay... |
