If I need a calculator more complex than the crackberry, I get my HP 48SX w/ 32k expansion card.

Oh, beloved calculator, how your saved scientific constants, convenient quadratic and cubic formula solver, and 3x4 matrix solver have simplified my life during the three years that we have been together. Your sleek and sexy design fits as if made just for my hand, while your beautiful textbook display is so much more intuitive than the nested parentheses of your Texas Instruments sisters. Alas, you have just failed me, and I am forced to cast you aside for your Titanium friend who sits unloved and unused inside my briefcase. If only your input held enough room for one more character. |

Haha! I can't even use the voltage-divider that way. You are once again the apple of my eye! No more cheating on you with that graphically-enabled hussy. |

I currently am using a TI30XIIS, and it makes me sad. |

Holy ****! Mathematica for smart phones. I think I just jizzed my pants. |

I don't have a droid. My current cell phone plan is the same as my father's, that being "whichever we can mooch for free from the family plan." |

I'd honestly just really like a good scientific calculator for my computer. The windows one sucks. |

The Win7 scientific calculator is a fairly standard scientific. It's just cumbersome to use a calculator with a mouse. I seem to recall the last time I had any reason to use it, I noticed there was a button or two that was missing, but I can't recall what it was off the top of my head. |

I'm still using XP though, and the calculator sucks. Mainly in the fact that it won't display in sci notation, and since I mostly deal in very large or very small numbers, I hate having to count zeroes. |

Honestly if I was to do really serious math like back in college, I would use a combination of Matlab and a Ti-89. Wolfram Alpha might be good too but I haven't used it much. Learning how to use Mathematica looks harder than the actual problems you'd solve with it. |

It will display in scientific notation if you click the F-E button in the upper left part of the calculator above the trig functions. I thought MatLab was dogshit compared to Mathematica. |

Thanks Coro! Most of the time I have my calculator on hand, but sometimes it's nice to be able to do quick calculations without having to dig it out of the bag/drawer I left it in last. I always preferred MatLab, but I used both. |

I learned how to use Mathematica first, over the course of my calculus classes. MatLab was taught to me later, via a one-hour course I was required to take where it was approached like a programming language. I **** hate programming, so you can see how that went over. MatLab also doesn't natively support piecewise-defined functions, which I thought was a big strike against it considering what everyone kept telling me I was going to be using it for. |

You can program in piecewise functions with just a few if statements. MatLab is essentially a (slow-running) programming language with good math and graphing libraries. |

The point is, I shouldn't have to. By this point in our computer technology, any CAS that can't natively support a concept we teach in high school algebra is a failure. It's like selling me a calculator that has no exponent button. Yes, I understand I can just multiply a number by itself repeatedly, but this isn't the 1970s. This software package has a FFT feature, but I have to write my own script to get it to recognize the Heaviside function? Think about that. I understand what MatLab is, that's exactly why I hate it. I don't like writing code. That's really the source of my beef. That, and the mandatory class we had to take on it covered the exact same **** as intro to programming. MatLab also suffers from piss-poor documentation. The help menu is a **** joke. Now, don't misunderstand me, Mathematica is not exactly the most user-friendly program I've ever put my hands on. MatLab handles matrix operations extremely well, but it chokes on symbolic operations. Mathematica handles these extremely well. Though, since it's come up, I'm kinda curious what Nephyr uses it for. Of what little chemistry I've taken (Gen Chem II), I have seen where an upper level chemistry major would be solving a system of differential equations, and where Laplace transforms would be handy. I also don't think a standard education in chemistry ever introduces the concept. |

I used mathematica and matlab - I prefer matlab but ended up using the former the mosts since the folks i was tutoring had to use it. I developed my own that was even better for what I needed it for, I'll have to find that someday. I suspect it's a POS now. |

Matlab is like a quick and dirty solution to scientific problems. For serious and in-depth models and simulations, I'd go with Java. I haven't used Mathematica but it's probably the best for theoretical math. |

What a bunch of pathetic nerds! I write ruby scripts for all my math needs (which aren't that complex). |
