:
: I actually got both calculators, TI-92 and HP-48GX, but I use the TI-92
: more than I use the Hewlett Packard. I just find it easier to use than
: the HP. TI-92 can solve things symbolically whereas the HP solves things
: numerically. Just try to integrate an indefinite integral like
: (X+3)/(X^2+2x+1) in the HP, it would be first easier to write it in the
: EQUATION WRITER. Then execute it, then collect, collect, collect, etc.
:
: Get the picture??
:
: Okay the pros of the TI:
:
: The TI is very easy to use, whereas the HP is very complex and
: confusing. The TI-92 would zip right through a simple equation,
: including calculus equation like differential or integrating, then give
: you the answer. Like I said before, the TI can solve thing symbolically
: whereas the HP solves them numerically. Mind you, sometimes the TI-92
: does give you weird answers and you do have to fiddle around with it to
: come to a simple solution, but at least it does a better job than the
: HP.
:
: The TI-92 has an Alphanumeric keyboard whereas the HP doesn't. HP is
: still like an old style calculator with numbers and function keys and
: its very hard to type. The common functions are right there on the
: keypad, but majority of the functions are accessible by a pulldown menu
: or all functions can be accessed popup catalog. HP also has popup menus
: for some functions like to integrate and differentiate, but it is still
: complicated to use, and you still need to put in limits even though it
: said it can evaluate an equations symbolically.
:
: TI also has an option called "Pretty Print." If I put in 1/2 which is a
: half, the TI can displays 1/2. HP, on the other hand, would display
: ".5". If I put in 1/2 + 1/4, the TI would return 3/4. HP would display
: ".75". So you need the decimal equivalent and not the pretty print? No
: problem! TI has a function key for approximation, and it WILL display
: the answer in a decimal form.
:
: The TI manual book, however, is mediocre. It's good and you can follow
: it very easily, but it doesn't go completely in depth on some examples
: in the programming of the TI. The HP??? HAHAHAHAHAHAHAHAH!!!! Forget it,
: dude!! The manual IS a frigging book, about some 400 or more pages. And
: its comes with two books. If you want more technical details and how to
: program the HP, you have to order $50 dollars more and you get two more
: volumes on the HP.
:
: Okay, that a pro, here some cons.
:
: TI-92 is new out in the market. It does have some support since TI's
: been out for a while, but the TI-92 is not very compatible with the
: other calculators. Then again, neither is the HP48 with the lesser
: models. TI-92 so far as I know of doesn't have any way of expanding like
: the HP does although there has been rumors of an empty socket in the
: back of the TI which possibly may be able an expansion chip. Now this is
: where the HP makes up for its weakness. In the top of the HP, you have
: two slots for expansion cards that you can put into it like extra
: memory, or specialized programs for chemistry, engineering, etc., plus
I beg to differ. The TI-92 will gain memory extension through Mel Tsai's
RAM Extender and that will give you from 512KB up to 4MB with a lower cost.
And I don't mind downloading programs from the Net. Other people can come
up with better programs than the manufacturer! Also, there is a lot of
support for it now.
: the fact its been out in the market for a long time. HP has more
: functions than the TI-92, like numerically be able to solve differential
: equations, whereas you need to make a program (or download one) for the
: TI. The HP has more programming functions than the TI, making it more
: flexible to program the HP. I've been told, but I can't confirm yet,
: that the HP has a built-in assembler.
That may be true, but have you checked out the possibilities of Fargo? I
think that would really whip some HP ass!
:
: I may have missed a few things but if you just need one to get by in
: calculus and physics, I bet on the TI92. IF you like gadgets and gizmos
: and don't mind wasting your time, and believe me you will, then go get
: the HP.
:
: Wanna see a comparison??
:
: First let me clarify one thing: the < > means a function key on both
: calculators. If I say for example <sin>, its the sine key function.
:
: Remember that integration I said before?? All I typed was (Integration
: symbol) ((x+1)/(x^2+2x+1), x) <enter> and the rest is history
:
: The HP?? To integrate you need the boundaries. It will not calculate
: without them. In Equation, <right upshift> Integrate, zero (required),
: <Right Arrow>, <alpha> x (required), <Right Arrow>, <right upshift> ( ),
: <alpha> x + 1, <Right Arrow>, /, <alpha> x <y^x> 2 + 2 <alpha> x + 1,
: <Right Arrow>, <Right Arrow>, <alpha> x, <enter>, <eval>, <Right
: upArrow>, <Colct>, <Colct>, <eval>, <eval>, <eval>. etc.
: Even If you use the popup symbolic menu to solve this equation, it will
: save time typing out the equation, but the answer is the same.
:
: TI Answer: Ln(|x+1|) - 2 / (x+1)
: HP Answer: (By equation writer and symbolic menu for integration)
: Integrate, 0, x, INV (1+x^2+2*x)*x + INV (1+x^2+2*x),x).
: After fiddling around with it for 5 minutes, I gave up.
:
: Funny thing is, it's not that much of a complicated equation. I would
: expect problems if I try to integrate the arc tangent on the HP, but
: this is ridiculous! This should be able to be solved by partial
: fractions / fraction decomposition and maybe even by parts and the TI
: comes through every time.
:
: I hope I helped you out dude.
