Carl McTague asked axiom to evaluate


\begin{axiom}
limit(sum(n**(-2), n=1..k), k=%plusInfinity)
\end{axiom}

while he was hoping for '%pi^2/6', i.e. $\frac{\pi^2}{6}$.

Any ideas?

I have no ideas how to move axiom to spit out the answer, but considering it should 
be $\zeta(2)$ I have another question: 


does the zeta function exist in axiom? It looks like in 1997, it had not been 
implemented.

fricas

There are no library operations named ** Use HyperDoc Browse or issue )what op ** to learn if there is any operation containing " ** " in its name.
Cannot find a definition or applicable library operation named ** with argument type(s) Variable(n) Integer
Perhaps you should use "@" to indicate the required return type, or "$" to specify which version of the function you need.
