Riemann Zeta Function of 4/Proof 5

Proof
From the Basel Problem we have:
 * $\displaystyle \map \zeta 2 = \sum_{n \mathop = 1}^{\infty} {\frac 1 {n^2}} = \frac {\pi^2} 6$

Therefore:

Taking the square of $\map \zeta 2$, we have:


 * $\begin{array}{r|cccccccccc}

\displaystyle \paren {\map \zeta 2}^2 & \paren {\dfrac {1} {1}} & \paren {\dfrac {1} {4}} & \paren {\dfrac {1} {9}} & \paren {\dfrac {1} {16}} & \cdots \\ \hline
