Hello everybody,

I attach a worksheet with some programms for root finding.

The programms made by me for a university work and I would like to share them.

Some of them, work only for the special equation f(x) , but the bisection method and newton work for all.

If something is not clear please let me know.

Every comment would be valuable for me.

Wladimir, hello!

I think that in your file there are no those comments for the program which you designated above (about methods and special equation).

You are right.

Here I attach the same worksheet with comments.

I think it's better like this.

Now it looks better. It is necessary to understand some areas of the document with text alignment and plots. Such this:

I used this graph when I was trying to find functions which converge to the desired solution.

The "fixed point method " (I think this is the correct name) is the only which is built on specially for f(x) function, i.e. the program (I suppose) will not work for any other function.

Nice video Valery.

I think that your programs are much more simple than mine.

Except from this, I got the opportunity to understand russian so it is more simple for me to understand your programs.
