Examples

Basic Examples  (1)

An error occurs because the symbolic parameter in the first argument of NProduct does not have a numerical value:

Wolfram Language code: NProduct[k ^ -s, {k, 1, Infinity}]

This shows a valid iteration specification in NProduct:

Wolfram Language code: With[{s = 2.3}, NProduct[k ^ -s, {k, 1, Infinity}]]
