I was hoping that someone could help me with a problem. I have alot of programs for my TI 83+ and they help me.. (sometimes) with math. I've posted many times on ticalc.org and basically I am a senior student who is taking senior calculus. I need programs that can show me the algebra involved with solving them. Example:
I found many programs that will help me solve logs.. but I get only a final answer.. I need the algebra to go along with it so I can really LEARN from it. Our class has a shortage of text books and no extra time (because of school funding cuts) so the only way I'm goign to pass this course with a decent mark is to learn myself.. and something that will make this a lot eaiser for me are programs that show me the algebra! I've found maybe one program that shows the algebra that is useful to me but I need some others. Below is a list of programs that I am willing to pay someone to code if they work properly and show all work/algebra needed.
1) Log Equations solver
2) Limits (demoniator of zero, root signs and all that jazz)
3) Derivitives
If someone could create a program for the TI 83+ that can solve those problems AND show the work (algebra) I would just be so happy! Anyone that can help me can email me at:

I'll post it on calcgames.org when done.

The actual code is done, but now I'm working on the interface.
It should be done tommorrow
It does algebra, all kinds except systems.
It has an incredibly high calculation speed.
You will see it here, it will be called KingSoft Advanced Mathematics software 1.0 |

Make sure it shows all the algebra so that I can learn from the steps and thankyou so much for the time/program! what does it calculate again? logs? limits? anything like that? congrats on the baby goat also, do you live in a farm? I live next to a farm and they have births a lot hehe.. but congrats and thanks SO MUCH for your time in doing this!

Total Posts: 27 | Okay This is my status report,
So far the program can:
Boot Up...
Log a problem...
And do some of the busy work nessecary to start calculation.
The program is VERY complex for me so that it is easy to use for you.
You just type in the problem and, when it is finished, it will spit ot the answer with all the work to make your teacher happy. It is large, about 2,587 bytes right now, I assume it will double by the time it is done, and it runs at an okay speed, (it would run fast on a S.E.)
I have developed new technology to help with this program, KingSoft Key Logger, capable of storing 9801 key strokes!!! Though the key logger in the program only stores 900 strokes (although I doubt you would use them all!!).

think ya could whip up something for limits? I just have a test on tuesday and I still dont understand limits.. but if you could get that going then your a WIZARD dude! absolute WIZARD! THanks so much for your time! We haven't started derivitives yet but were doing that next week so there is time for that one but limits is the hot topic of this week! I can throw ya some cash for your troubles dude!
Thanks again for your time.

Also no money is nescessary, I'm doing this for the greater good, TO STOP BITCHY MATH TEACHERS!! I hate showing my work also. Check back tonight, If it is done I'll have a download link in this forum.

Here is the site I found

They explain it very simply

Total Posts: 15 | Hey there:
well luckly i did well on the limits test, but they are getting really hard and that program would be really swell to have. If you could make that program to show all the work (algebra) needed to solve limits that would just be awesome. Even if it takes a little bit, because limits are important in calculus and I have alot of programs that evaulate them but show no work.. but your doing great thanks so much KingSoft! Also, do you think you could write a program that evaulates Derivitaves? Were moving into that and derivitaves are KEY in calculus! Ok man thanks for all the great work, hope to hear from you soon I hope :)

I'm at school ALL DAY (till 9:30 tonight!) so I wont get a chance to move forward today.

gl on that Alex!

Total Posts: 2486 | Lol, I just let my calc do them :). You Gavin could probably email KingSoft and ask him how he's doing. Unfortunately not many of us remember how to program 83x so we couldn't be of much help. I'd btw suggest you have a look on Ebay, maybe you could get a nice deal on a TI-89. My friend got one off of Ebay last year for like $50 (and it was new and factory sealed!). TI-89 can graphically do derivatives, though, even 89 doesn't show work if that's all you need.

Total Posts: 1676 | it's not just grahpically - there's a derivative function that does stuff even too advanced for me. it'll do implicit differentiation and will even graph a first derivative (for some reason when i tried to graph the 2nd derivative (using 2 d(d('s as opposed to writing the actual expression) it didn't work right... maybe i did something wrong).
but basically, the 89 will do anything. There have been 2 or 3 types of integration problems that it will not perform, but usually it works great.

Total Posts: 2486 | :) yeah, 89 is great. TI calc king perhaps. it's however a little pricey for some. though, those who intend to get 83+ SE should definitely consider 89 instead coz its just $10 more but will provide many more features.

(Well, it turns out I teach the teachers how to use it). But I want to get one of those. Which one would you calculator gods reccomond, the 89, 92+ or voyager? |

Total Posts: 1051 | I would go with the 89 over the 83plus any day. In US dollars the 89 is about 150. It's worth every penny, trust me. I've had mine for 5yrs and have dropped it onto tile (accidentaly) 30+ times and it still works just fine. For information on the 89 go to this url. BTW I'm not 'late'. Since I know about nothing for programming on the 83plus I had no use in here :-D
http://education.ti.com/us/product/tech/89/features/89bid.html
allynfolksjr: It depends on what you are going to use the calculator for. If you still need to take standardized tests (ACT, SAT, AP etc) the get the 89. If you are past that I would recomend getting the V200 because of the larger screen, more memory, and QWERTY keyboard. On TI's website they say the V200 is an update of the 92+. Don't worry about compatability because within a month (at most) I would have to say the issue will be obsolete. Here is the V200 info.
http://education.ti.com/us/product/tech/89/features/voyagebid.html
BTW there is 960KB of Archive memory! Thats 983040 bytes. I have 17 games, Edit 3D with 24 models and 11 textures, 20 Space Dementia ships, various enhancements, two books of the Bible and a whole lot more. Total 142 files, average file size is 6505.56 Bytes. Oh, add NoteFolio and StudyCards to the list.

Total Posts: 2486 | yeah, TI made a rather idiotic thing and chopped more than half of v200's memory off for apps...which very few of us use and need soe much memory for. i hope this is only a software limit which will go off soon. either way, v200 has a lot more memory than any other calc, even 83+ SE (if you look at combined mem). also, 89 has more ram. having so much archive and such tiny ram on 83+ SE makes you wondering why. anyway, if you can learn you calc yourself, go with 89. this way kids in you math class will have to do everyhitng by hand and you'll have your tursty 89 do the work for you (make sure you do learn how to do things yourself too, though). hehe.

Also if you can actually fill up all the APP portion of the Flash you won't have enough RAM to do jack. Its really stupid. Only 960KB of the FLASH memory is user accessable. |
