Can you calculate Pi using a Solver (on the prime)?

Tried this on the prime but it appears that the solver doesnt support recursion

Just a terminology issue: it's not recursion, as you say, it's nesting.

The Solver (FNROOT) instance isn't calling itself (recursion), it's the function being solved the one who's calling another instance of the solver applied to a different equation (nesting).

Think of integration. A double or triple integral isn't recursive integration, it's just nested integration.
