    Calculators TI Nspire or Casio Prizm

    Hi all, I know this is very subjective and probably ask a few hundred thousand times. I'm an mech engineering student looking to upgrade from my ti 83. I know atleast so far my math classes wont allow a CAS capable calculator, and that you can get the interchangable keyboards to remove that...

    Calculators TI-83/84 sets of numbers/set theory

    Here's what I want to do on the calculator. 1) Input sets of numbers, for example 3,6,9... in any notation, for example {3,6,9,infinity} or {x|x/3 >= 1 >= infinity} 2) use set theory (not now, but when I get into pre-cal/college.)

    Calculators Vector capable calculator recommendations?

    I'm taking a vector analysis course this semester and would like a vector capable calculator. For calculus I have been using a TI-83. Any recommendations? Price not an issue, but as always its better to get the job done for less. Thanks!

    Calculators TI-83/84 Plus - Storing polynomial functions

    Unless I'm missing something here, I've noticed that if you want to store a polynomial function on the TI-83 or the TI-84 Plus, you have to create a program that asks you what the value of x is, then displays the value of f(x). I kind of wish I could define a function without making a program.

    Calculators (-i)^4 = Domain Error?

    I'm curious if anyone knows why my calculator would return "Domain Error" when calculating (-i)^4 on my TI-36X Pro? ((-i)^2)^2 works just fine on the machine, and (-i)^4 works just fine on my TI-83 Plus. Any ideas?

    Calculators Calculator giving weird answers?

    For sin(4pi), my calculator gives -2^-13. Obviously, that is really close to the correct value of 0, but it just says 0 for ANY other multiple of pi I've tried. Weird right? TI-83 plus.. common calculator. Anyone have issues like this?

    Calculators Where to get large display (Like TI-83) calulator that is non-programmable?

    My Fluid Mechanics teacher doesn't allow programmable calculators and he checks before the exam. I asked him and he said we can have any large display calculator as long as it isn't programmable. Has anyone seen such a thing? I really am dependent on the giant LCD that shows the equation after I...

    Calculators TI-89 and HP 50G?

    The main difference between the two (other than the RPN which I don't care much about as I am already used to using a TI-83 which doesn't have RPN) is that the HP is powerful, and the TI has more 3rd Party support. Of that though, the things I care about most is that you can expand the memory of...
