Newton's Method

Forum Attachments

Summary:

There is no page on this site (at least that I have found) explaining how to use the variants of Newton's Method in TI-BASIC. I want to help create that page. Where should this page be placed?

Newton's Method

To my knowledge, there is no page on this site discussing the variants of Newton's Method for TI-Basic calculators. If I create this page, where should it be placed? Also, if anyone has any information about programming Newton's Method, I would appreciate it if you would post that information to this thread so I can incorporate it into the dedicated page.

These are the variants I have so far. If anyone has a better version of the ones below, please let me know.

For Y1=0:

For(I,1,10)
Tangent(Y1,A)
A-((Y1(A))/(nDeriv(Y1,X,A)))→A
End

For Y1=Y2

0→I
Repeat I=10 or K<20
I+1→I
0→K
10rand→A
Ans→A
K+1→K
A-(Y1(A)-Y2(A))/nDeriv((Y1-Y2),X,A
End
End

Yay, more programs! :D

I suggest the programs section or the routines section under Math. Use this link to make the page. Remember to link it to whichever section you choose.

EDIT:Also make sure to use the given templates on each page.

I may not have the page complete tonight. I will probably finish it sometime tomorrow. Then someone is going to have to look at it because I have no idea if it will follow the template by the time I am done with it.

Someone may want to finish the Newtons Method page, because I think I screwed something up somewhere.

I'll do it! :D

EDIT: Well actually, this isn't a problem! To revert a page to its previous form, scroll to the bottom of the page, then click on "History". From there, see which page you want to revert to, then click the "R" button to revert to that page. Clicking "V" allows you to see the page version without modifying the page itself, and "S" allows you to see the source code of the page.

In short, I fixed it for you :D

I think I finished the Newtons Method page. If anyone sees anything that needs to be changed, please let me know. I also added a link to Newtons Method on the Routines page.

There is an error:

Repeat I=10 K<20

Was there something in between "I=20" and "K<20"?

It is supposed to be this:

:Repeat I=10 or K<20

I'll fix that.

EDIT: Just fixed it.

Nice! Put the program in a file download :)

That'll take me a few minutes, since I have to use Cemetech because I lack the software to upload programs straight from my calculator. On it right now.

EDIT: I saw that you put the program in a file download already. I misunderstood "Put the program in a file download" as "You go put the program in a file download." Thanks for doing it for me! :)

No problem! I'll try to be more clear in the future, that was totally on me :D
