This category contains pages concerning Limit to Infinity of Summation of Euler Phi Function over Square:
- $\ds \lim_{n \mathop \to \infty} \dfrac {\map \Phi n} {n^2} = \dfrac 3 {\pi^2}$
where:
- $\map \Phi n = \ds \sum_{k \mathop = 1}^n \map \phi k$
- $\map \phi k$ is the Euler $\phi$ function of $k$.
Numerically, this evaluates to:
- $\dfrac 3 {\pi^2} \approx 0 \cdotp 30396 35509 \ldots$
