Sorry, my math and English are poor, but I still want to ask a question about π(x). If we let x/ln(x) be substituted into x, and so that becomes to be [x/ln(x)]/ln[x/ln(x)], then repeat this step over and over again; thus, is it correct that finally equals π(x)? Would someone like to explain to me if that is correct? |

repeated iteration of $\dfrac{x}{\ln(x)}$ results in $e,~\forall x > 1$ $\dfrac{x}{\ln(x)}=x$ $1 = \ln(x)$ $x = e$ $e \neq \pi(x)$ |
