Homework Statement


B=1/(1+(1/1+(1/1+(1/1+(1/1+...

what does B equal?


Homework Equations



I don't believe there are any...it's a conceptual question.


The Attempt at a Solution


Would it converge to 0? My reasoning was that if 1/(1+1)=1/2, and then 1/(1+1/2)=1/(3/2)=2/3, and 1/(1+(2/3))=1/(5/3)=3/5, and 1/(1+(5/3))=1/(8/3)=3/8, etc...

There's usually a way to algebraically manipulate this into a quadratic or similar problem. Have you tried that?

I can't quite remember how it goes, though...
 
Oh, I remember.

Take a look at the denominator. The denominator CONTAINS B, as long as the series is infinite.
 
Thanks for your help!
 
No problem.
 
There are two things I don't understand about this problem. First, when finding the nth root of a number, there should in theory be n solutions. However, the formula produces n+1 roots. Here is how. The first root is simply ##\left(r\right)^{\left(\frac{1}{n}\right)}##. Then you multiply this first root by n additional expressions given by the formula, as you go through k=0,1,...n-1. So you end up with n+1 roots, which cannot be correct. Let me illustrate what I mean. For this...
