Just ordered one. How do you guys like yours? Seems like it is pretty badass and powerful. Is it any faster than the old ti-89?
franznietzsche said:Fourier expansions of functions is one thing i do that takes time. Programs take up cpu cycles as well. Data spreadsheet manipulation. Things like that.
You have to realize that modern calculators are essentially mini-computers.
graphic7 said:In that case, it's much faster to use something like Mathematica or Maple. Why would you need spreadsheet manipulation on a handheld device? If anything, drag a laptop along with you that has Excel/Mathematica/Maple/Matlab installed. That, in my opinion, is the best package.
I seriously have not used any of my graphing calculators in quite awhile. I'm mostly seen hauling around my HP 32SII, and it does a very good job at racking up some calculations. If I ever find myself needing to know an anti-derivative, there's usually a CRC book or computer with Mathematica or Maple installed within proximity.
franznietzsche said:Its much more convenient. Its about the right tool for the job. I can enter in ten quick data points into a spreadsheet on my calculator, and then get a linear regression, and graph said function faster than i can get a spread sheet program opened on a computer. SO no, its not faster to use a computer.
A computer would be overkill for what i use the calculator for. When i actually need a computer, i'll go and work on that. For quick problems, its utterly unnecessary. And far more expenseive to just buy a laptop and a copy of maple for those purposes.

Most high schools do require TIs. Considering the way math is taught in high schools, stating that the TI is required in one is not much of a compliment.Tom McCurdy said:The reason most of us have calculators is for our math courses. In my high school the TI is required.
Considering you can't figure out how to burn an ISO image, this tidbit is insignificant. Is it painful to drag around a 3lb laptop?I can do things on it simply quicker than I could do on the computer. The thing is very convient, I don't want to be dragging a computer around with me.
TIs are notoriously slow on matrix operations as well as most of it's CAS functions, such as differentiation and integration. If it's not in it's table, you're going to be sitting there awhile.As for processing speed, it does matter. Programs can run quicker with faster processors... as can things such as generating graphs.
Honestly, how many calculator brands have you worked with and can use proficiently other than TI?The Titanium is the most amazing calculator you will ever have worked with most likely. It simply is awesome.
