Post your ideas for new math programs here, or build on ideas posted by other visitors.

Ok you people out there that want the easy way out in your geometry, algabra, and pre-calc class
i got a math program for you that does most of what you need for these classes.
ne thing from: Area, surface area, volume, cramers rule, Conics, distance formula, end behavior, midpoint, pascals triangle, quadratic formula, reducing radicals, and slope.
It runs right out of the program menu, or if you really want to be secretive, it works under mirage (which can hide it from teachers)
I was hoping to sell it for like 2 bucks....but don't know if it will work that way... but if you want it..email me and i'll give it to you for free

I am 14 and need an algebraic binomial and trinomial factoring source code. I do not have an uplink cable so please send me the code.

Because I like to help people learn programming and stuff, I have setup a few yahoo groups where people can learn from me/eachother, share files/programs, post messages, etc. - Trust me, I am among the best, so I think it would be very beneficial.

I am very willing to teach people everything I know whenever I have free time (I like to work on a one-to-one basis). Check out my groups if you are at all interested or curious.

Below are the web addresses for my groups (CAREFUL, I had to put a space after each slash, so if you copy and paste, delete the spaces):

http:// groups.yahoo.com/ group/ TICALC101 - deals with ticalcs and stuff

http:// groups.yahoo.com/ group/ PROGRAMMING101 - deals with programming concepts, applications, and graphics in general

http:// groups.yahoo.com/ group/ CppJAVA101 - deals with C++ and Java

can someone help me create a program to find a remander of two divided #'s??

by the way i have a ti-83+se calc if that makes ne difference

Yes, it's called mod(), short for modulus.

mod(a,b) gives you the remainder of a/b.

where is the mod() botton??

*****on a ti 83+se*****

It appears the TI-83+SE doesn't have the mod() function. Sorry about that. (I don't have a TI-83+SE).

Anyway, here's a way to compute the modulus of A and B and put the result in N:

If B:Then
A/B->N
B*(N-int(N))->N
If N<0:N+B->N
Else
0->N
End

You might have to tweak it a little to get it to work, but I think you get the idea.

hey i was wondering if u could help me w/something else could u create a programm that changes one base to another for example:45 base 6 converted to base 2 thx

You could try searching for one first. For example, you could probably find one or more in 83plus/basic/math (such as baseic.zip or bases.zip) or in 83/basic/math.

I don't want to sound rude or condescending, but you really should look first for what you want before you ask someone to do something for you. This site especially has most math programs a beginner like you or I would need.

Once you've learned enough and need a program that doesn't exist (at least on ticalc), one should hope that you would have the ability and knowledge to write what you need by yourself or at least to search the many resources available to you on the Internet and other places. This goes for most every beginner, not just you.

I'm not trying to be high and mighty by calling you and others a beginner; I still consider myself to be a beginner in many ways.

A simpler way is to simply multiply the fraction part (fPart in the catalog) of the quotient (answer) by the denominator (the # you devide by)
ex) in 65/3=21+2/3, you would take 2/3*3, which is 2.

a better way is just round(BfPart(A/B)). the round part gets rid of any mistakes the calculator makes for only going out to 14 decimal places for calculations.

Thanks

to find the remainder of a/b:
fpart(a/b)--fpart is math-num-4
ans*b

OR

a-(ipart(a/b)*b)--ipart is math-num-3.

i think even an 83 has it, certainly an 83+ does.

You can type fpart or ipart into the 89, 92, Voyage, et c.

hi i am taking AP Calculus. please, i am begging you. someone has to create a super program for this class. it isn't a hard class, but it takes time to solve some stuff. also, a calculus program would save me time in contests. well see you and thanks

There already is one out there. It is - I believe - apluscalc.zip.

A lot of programs calculate everything for you in the background, giving you a final answer. What about a program that gives you the formula? I can't remember formula, and I don't trust values of programs, I'd prefer to just see the formula.

just look in the source code.

Does anyone know and could tell me how you edit your programs so u can't edit it

Option 1: If it is Mirage compatible (add a ":" to the beginning of the first line), you simply highlight it in Mirage and press "tan(". To the right, the properties should read either "LOCKED:Y" or "L:Y".
Option 2: Send it to your computer (PC or Mac) and open it with 83+ Graph Link. There should be a box next to "Protected". Check the box.
If you don't have either of those two programs, e-mail me at SSpyro64@AOL.com

Ok, this is kind of similar.
I'm the only person at my school who knows any bit how to program calculators, so, like anyone would do, I sell them. However, lately, people have been giving each other the programs instead of buying them from me. Is there a way to stop people from being able to send programs????

Thank You

thats pretty underhanded ... but, back to the point if you aren't sending then mirage its easy to send them a shell that can detect hidden progrsms and run them but not unhide them. You can send them the program from mirage so you dont have to unhide it. they will be able to run the program from the shell but if you dont give anyone mirage then they cant send them.

there is also an asm program out there for the 83+ tht has a hide/unhide function called Options. you can use it
