i checked the multiplayer codes, but its not for having
multiplayer poker games where you have 2 or 3 ai players and one human player
can someone plz help
DarkerLine 1218484234|%e %b %Y, %H:%M %Z|agohover
"Multiplayer" usually refers to games with more than one human player, so the multiplayer page wouldn't be useful to you. What specifically are you interested in?

It sounds like he's probably interested in AI. Is that right, larry4624?

My TI-89's catalog is incoorect. Instead of having a catalog with user defined functions and variables along with the prestored commands, I have a catalog that resembles that of a TI-83, and contains only the calculater functions. Anyone know how to get the correct catalog back?

there is a symbol i am trying to program, tha a with a dash over it, but i cant find it anywhere on my calculator. can anybody help me?
noahbaby94 1225132508|%e %b %Y, %H:%M %Z|agohover
Do this hit Vars button 5 button and then scan through the menus there some cool symbols there. If you cant find it there use this program.

I need help with symbols too. i need the a with a dash, but i also need the little triangle before things like (^=triangle) ^X and ^Y and ^Tbl, but i need it separate, by itself.
Timothy Foster 1225138613|%e %b %Y, %H:%M %Z|agohover
You are talking about delta, right? 
I went ahead and downloaded the program noahbaby94 introduced, and it includes that and a variety of other symbols. I would recommend downloading that program.

Ahh i finally see what you mean you get ΔX and ΔY from the vars menu go down to 8 and 9 and you'll see both of those. For the ΔTbl go from the vars menu to Table and hit enter It will be the second one.
P.S. I suggest you play around in the vars menu.

Does anybody know how to make a program so that the TI-84 (or preferably just any TI calc) can print out a number that's longer than 14 digits long? When i try to subtract two numbers bigger than that (eg 1234567890123456 - 1234567890123400) I end up losing any digits after the 14th (that problem returns 0, when it should be 56).

unfortunately, i don't think it's possible
Timothy Foster 1237154451|%e %b %Y, %H:%M %Z|agohover
The calculator only remembers the first 14 digits of any number, and it displays the first ten digits. So really, I do not think there is a way for the calculator to do this. There might be a program that can do it.
EDIT: Here is a program that says it can do it. I haven't tried it, though.

this is just a guess but…
when i read about assembly, i learned that the largest registry in the calculator is 2 bytes, which is 16 bits. the largest number represented by 16 bits is a 14 digit number so the calculator can't handle math larger than that (i'm guessing?)
if somebody were to write an assembly program that used memory addresses to do the math…

Is it possible to write a line in a TI-84+ program to change the value of a yn expression? Specifically, I want a quick way to fill y3 with nDeriv(y1,x,x). (I'm making a program to automate the process of checking whether a derivative I've found for Calculus class is correct). My code as it stands now is:
ClrDraw
FnOff
DrawF nDeriv(Y1,x,x)
GraphStyle(2,2)
FnOn 2
The idea is that you'd input a function as y1, input what you think its derivative is as y2, run this program, watch the calculated derivative be drawn, and then watch the guessed derivative be drawn in bold; if they overlap, you were right.
Since I couldn't figure out a way to get my program to force the expression "nDeriv(Y1,x,x)" into y3, I used DrawF, but the calculator clears the drawn function before drawing y2.
…Help!
Timothy Foster 1238964588|%e %b %Y, %H:%M %Z|agohover
You can store nDeriv(Y1,X,X) into Y3 directly through the Y= editor. If you want to store it withing a program, you can do this:
"nDeriv(Y1,X,X→Y3
You can store a string into a function variable (therefore, the quote is needed).

I am working with a TI-89 and am trying to control an external device with the serial port. I have a 2.5mm stereo cable which is properly connected to the calculator and pull-up resistors on the data lines. The output should be visible on my oscilloscope but I don't see anything. The calculator then spits out an error "Link transmission". Is it waiting for some form of return?
0h55 -> t
while (true)
send {t}
EndWhile
For testing I want to continuously send 55 hex as fast as possible. So can I ignore the error in basic or do I need to do this in assembly and will I be able to turn the calculator off short of removing the battery if this works? Eventually I will be controlling a RC car like robot and maybe make it follow a user input path (sin, cos, parabola, etc.).

I don't know about the 89, but on the 84, it the usb, and I would assume the I/O port, uses Bulk transmissions in forms of packets. So I don't really know.

John Edwards (guest) 1244576971|%e %b %Y, %H:%M %Z|agohover
But both the 84 and 89 still have the serial cable port so shouldn't I be able to use it? Either way how do I get around the error?
graphmastur 1244580060|%e %b %Y, %H:%M %Z|agohover
I looked at the error page for 68k calcs, and We don't have much information on it. Just the name, and error number. I don't know of a way around it, except through asm.

my daughter is using the 83 Plus to do some graphing problems. However when she pushes graph it says ERR: archived. How do I get this off.
bxsciencer 1257118389|%e %b %Y, %H:%M %Z|agohover
maybe the Plots are on, but the lists are in the archive?
to get to the archive, press:
[2nd]
[+]
[2]
--------------
once there, to get to the lists, press
[4]
if there is a star next to the list, press enter when the arrow is next to the list name.
with the star, it means its archived
another way to do this is:
[2nd]
[+]
[6]
[2nd]
[STAT]
-----------
find the list name
press enter
press enter again
hopefully this works

The easiest way to remidy this is to reset all default settings.
Press [2nd] [+] [7] [2] [2] to do this. This will not erase data in RAM or ROM. If there is "giberish" (Somthing your daughter accedintally typed in) in the y= menu, manually clear these.

hey, I have a ti 84 SE and have a pretty dumb question, but nonetheless a question. I used the Horiz command(splits the screen in two between the home and graph screen) and now I dont know how to get in back to normal. Thanks if you reply
jstuffjr (guest) 1257305016|%e %b %Y, %H:%M %Z|agohover
sorry, just realized I did a typo. ON the second line I meant to say "and now I dont know how to get it back to normal"
jstuffjr (guest) 1257305427|%e %b %Y, %H:%M %Z|agohover
Okay, I just figured out how to fix it. Pretty obvious, don't know why I didn't see it before.
