does anyone have a program or other way to simplify radicals like ��8 = 2��2

Hi everyone....I'm looking for programs dealing with sequences and series for Calculus BC....any ideas?
Thanks

Does anybody have a program for a 73 that can find GCF of two numbers? I am supposed to right one for a class.

Does anybody have a program for a 73 to find the GCF of two numbers?

I like to use TI-BASIC, and I was wondering how dou you make vectors with BASIC.

HELP!!!!! lbrogan2@gmail.com

Does anyone have any easy programs that could help with the SAT. Plus, if you have programs to figure out angles and sides using law of sines.
PS- Could you type it out so that it is step by step, I'm a beginner and I don't have the wire to upload the program from the Archive.

I'm not going to type out the whole thing. But here's a start, and I'm sure you can figure out the rest.
Normally, I'd use a menu function, but you said you're a beginner, so I'm going to show you how to do one program for each function.

Input "angle A", A
Input "angle B", B
Input "side B ", E
(E/sin(B))sin(A)->F
Disp "side A"
Disp A

You can input other things and output other things, using either if-then statements or separate programs. I would recommend the former, although if you don't want to write programs that long, then just create like nine different programs.

You can use the law of cosines, too.

I been trying to figure out how to be able to scroll right of the prgrmIO screen, because sometimes when an list is displayed in my program it does not display completely and part of it is right of the screen (which I cant scroll to).
Browsing through old posts here,I saw someone that also asked this a while ago but no one answered. Hopefully someone can answer this to me... I mean I am sure this happens to a lot of people but somehow they seem to know the answer. Thanks in advance.

Hello everybody!
I would be very pleased if someone directs me towards the mathematical techniques that are used to solve puzzles.

Does anybody have and/or know how to make a program that alows me to divide a trinomial by a binomial?

I need some help, I'm trying to see if there's a way to write a program that reads feet and inches (fractions).

i was wondering
if there is any way to make a program that will reverse the digits of any number

ex: 3425 becomes 5243

i need a program that reverses the digits of any number

ex: 321 to 123

Took me a good 10 minutes, not to hard...

Clrhome
1->T
1->M
0->C
Input "Number",A
While A/M>1
M*10->M
C+1->C
If C>16
Stop (Because then you'd get an error, not enuf space on screen to fit 17 chars. you can add stuff here if you want like an error message)
End
For(J,1,C+1
iPart(A/M->L
A-L*M->A
M/10->M
L->L1(J
End
For(J,C+1,2,-1
Output(8,T,L1(J
T+1->T
End
Pause
Stop (Optional)

Good program for distance, slope, midpoint.
:ClrHome
:Disp "(x1,y1)"
:Disp "Enter x1"
:Input A
:Disp "Enter y1"
:Input B
:Disp "(x2,y2)"
:Disp "Enter x2"
:Input C
:Disp "Enter y2"
:Input D
:(A+C)/2 STO E
:(B+D)/2 STO F
:Disp "X Is",E
:Disp "Y Is",F
:Pause
:(B-D)STO G
:(A-C)STO H
:If H=0
:Then
:Disp "Infinite Slope"
:Goto A
:End
:(G/H)STO I
:Disp "Slope Is",I
:Lbl A
:SQRT((H*H)+(G*G))STO J
:Disp "Distnace is",J

Can anyone post the code for a program that solves systems algebraically by substitution and Elimination for two equations. For example:
3x + y=15
2x + y=11

Also if anyone knows any websites that give just pure code and not downloadable programs, please post it up

I think this should work.
I'm gonna check it on my calc.

ClrHome
Disp "AX+Y=B"
Disp "CX+Y=D"
Prompt A,B,C,D
B-D→θ
A-C→Z
C/A→X
AX→W
B-W→Y
ClrHome
Disp "X=",X
Disp "Y=",Y

Here's a pretty cool program. What you do is select 3 points on a coordinate plane. going from one point select randomly one other point and plot the midpoint. From the that new point select randomly one of the 3 ORIGINAL points and plot the midpoint. Repeat this a couple hundred times and see what you get. I am not going to put up the coding unless someone asks for it. I used 83 BASIC. Check out the result its pretty cool.

would anybody know a good program for like area of shapes that i can make to put on a ti-83 plus??? i just need somebody to teach me how to program and enter the data...

Well, all you would have to do is determine whats the max number of sides you would need and determine how many triangles you can get from diagonals in that figure. There is a equation for this somewhere. It would take some time to create though. Email me and I could start working on this. . . .
