I wanted to know if anyone knows how to store formulas/equations on a Ti 83.

 

you can save them in a program if you want but i dont know how to make it to where you can plug in variable and it calculates them for you

 

what he said. you can just store it as text or a string in a program or can actually write a program. the program can ask for input and using that input, calculate the formula that you programmed in and spit out an answer. 83 programming is like basic level java or some other language

 

where do you get the program? or is it in the calc? I just need to store equations for chem lab because I hate having to have big spreadsheets of equations.

I know how to solve but cant remember them all.

 

DudeI can even write english.

 

you press the PRGM button and then hit new, type in a title, press enter (to go to the next line) and then start typing in your formulas on the lines. to see them later, go to PRGM then EDIT and choose that program

 

thanks I'll try that

 

This sucks I tried to write a program then go back to it and I ended up deleteing it. Is this calc really supposed to store functions?

 

Its not suposed to store functions that arent built in, but you can write or download a program to do what you want it to.

what are you trying to calculate?

www.ticalc.org will probably have a download for it if you have a usb or serial cable for your calc. If you dont have one, i suggest buying one.

and FYI..the easist way to program a calculator is with the BASIC laungage..its very..basic and easy to learn

 

I want to store basic Chemical formulas like:

A+C=D

K=[D]/[A][C]




and so forth

 

all you have to do is what i said above. go to PRGM and then create a new program, give it a title on the first line and press enter to get to the next line. type a new formula on each line (it wont looks all pretty and formatted but you can get it in there) and when youre done, do a 2ND + QUIT. when you want to view what you wrote, again go to PRGM, then go to EDIT and choose the program you made. dont press any buttons in there besides up and down. when youre done with that, again 2ND + QUIT. theres not much to it.

 

^^ alright 2nd and quit got it. I wish I would have known that before I deleted them on accident.

thanx

 

Aren't those things somewhat obsolete with all the cheap palm pilots and all the software available for those?

 

Kinda,

 

Kinda, I have a PPC and it's awsome but we are not allowed to have cell phones in the lab. and I already have the calculator.

 

nope, those are definitely not allowed on standardized tests and rarely on regular tests. theres not much learning involved if you just have to give the calculator some numbers and it figures it out for you. not even 89s are allowed on some tests like the SAT

 

I realize that, I just figured that programmable calculators would be past their prime with hand held computers and such. They are the same price, size and have far more features.
