I do not know the extent of it. I only know I miss him.


In mathematics, you don't understand things. You just get used to them.
I have the result, but I do not yet know how to get it.

Re: Try this personality test.

You undoubtedly used the methods of ordinary algebra but there are many numerical ways to get the answer too.

I have to go cook, see you all later. Have a good day at school.

Re: Try this personality test.

Will you cook in Angela Style or Gangnam Style?

I know two ordinary algebra methods and one numerical method and also the CAS way and also the graphical way and also a brute force way, Newton Raphson, Midpoint attack if they count

Re: Try this personality test.

There are many ways to solve equations numerically. The interesting one here is doing x_0=... x_n=3+1/x_n-1. It can even be done on a scientific calculator.

What use is the quadratic formula in our daily lives? Can we use it to unlock the secrets in the hearts of those we love?

bobbym style.

You can solve that also by converting to a continued fraction.

That is it, you understand the idea. To compute the answer what would you do?

Re: Try this personality test.

I would convert it back to a quadratic equation and use the quadratic formula.

I've always changed those continued things into a quadratic and then solved it, never tried the other way round

Supposing you left out that end 1 / x what would you get?

Re: Try this personality test.

To one of the roots of your equation of course.

Can you do that one or need me to?

The process is pretty much what I described in #80.

Re: Try this personality test.

That is the same process. There are many iterative methods too.

I kniw about Newton's method, the tangent method and the secant method.

Re: Try this personality test.

Those are methods that have names and use geometric ideas. They are very popular in books written by people whom never solved anything other than a book problem.

Did we cover any of Forman's ideas for iteration?
