Indeed! In the old days we actually had to solve these problems without calculators! :Q

I used a slide rule 😕

A slide rule? Wow. I've seen a few of those in museums. 😛
 
Anything higher than calc2 really does need not a calculator. Why do you need a calculator for infinite series? I wish my prof barred us from using calculators in calc3, then maybe i would have actually learned stuff. And Differential Equations, I find the calculator almost useless in that class. I did fine w/o a calculator, but after i strated using one, my grades went down🙁

For Calc3, we aren't even allowed to use a calculator (any calculator!).

As much of a calculator geek I am, that's the way to go! Learn to think for yourself. One day, you might be the guy designing the calculator.
 
The people that design the calculators use substantial amounts of computing power to design the logic that makes up the calculator. Therefore, your theory is flawed.
 
The HP49G is superior to the TI89. Plus it has RPN, which is just icing on the cake.

EDIT: BTW, I was trying to get one for a friend a couple weeks ago, and while I knew they stopped producing them, I didn't realize that they're impossible to find now. The only place I found them was on amazon, from some retailer selling them for $300.... They used to only be $200... heh. Maybe ebay?

What's cool about the TI-89 is that it has a 68000 CPU in it -- the same CPU used in my first 16-bit computer -- the Atari Mega ST4.

and it can be easily overclocked 50% in the ti series calculators, really speeds up graphing complex functions

yeah only thing my ti-89 was good for in DiffEQ was typing in formulas and steps for when my mind goes blank.

What's wrong with the 49G+?

I don't think it's out yet... And it's going to have hard buttons... Bleh. Rubberized buttons are awsome, as long as you didn't get defective ones that chipped. heh.

I go to UCLA and I picked up a hp49g+ from out student store for $140 ($10 cheaper than online plus no shipping).

In class, our prof put up this complicated RLC problem and he was trying to work it out. I inputed it onto the calculator, hit enter, and it was literally simplified in 1 second.

It has RPN and Algebraic mode so the learning curve isn't too steep.
 
i'm now in 3rd year comp eng (first 2 years of which are shared with ee's) and haven't had to use a graphing calculator yet (except in highschool where it was required). in fact in most of the courses, graphing calculators aren't allowed on tests, and when they are allowed, they aren't much help anyway.

and you think a ti-89 isn't powerful enough LOL
 
Dont know why you lot are bitching about the Ti-89 because it doesnt have RPN. I have got an RPN shell for mine. Interface is much nicer than the 49G. OK it can be slow at graphing. But if you can find a function it cannot do you can either input it yourself easily or just download it.
 
I always thought if you could put things like 5318008 and 0.7734 upside down that was enough to qualify for a good calculator 😕
 
their profit margins must be insane on those things. they're basically overgrown game boys, so it's 1989 technology with a crappier screen for $100+.

reverse polish notation

google it

basically instead of writing things like (1+3)*4
you write

1 3 + 4 *

😕 Polish people.

when you get used to it it makes entering expression easier

eg if you hav something like
((3+2)*(2/3)+3)/((2+2)*2)

you just enter it like

3 2 + 2 3 / * 3 + 2 2 + 2 * /

the order is the same as if you were doing it by hand so it much more natural and the lack of brackets make it faster to entire

i got my ti83+ for almost 100 (cdn). i got my toshiba 300mhz ppc for 250. :|

THe buttons are already small enough.

I have used every single button on the 89 at least one point in my life. There's no way they can make it smaller. I already have to go to the catalog for such basic functions as log10...because it isn't even on the keypad....

how about thinner and lighter?
