The Swiss mathematician Leonhard Euler demonstrated two and half centuries ago that the series...

... diverges, so that diverges also the product...

However, if then,

So, can extend the formula,

@chisigma thanks for the help! however I am still a bit unsure on how the divergence of the sum implies that the product also diverges?

@FernandoRevilla cheers for that! I haven't seen that formula yet, nor can I find it in my notes, however im very interested, can you perhaps show me a proof of how the formula comes about?

thanks again! - March 30th 2011, 10:41 PMFernandoRevilla

In...

Convergence of Infinite Products « The Everything Seminar

... there is the proof of the following theorem:*an 'infinite product' of the form...*...

... converges if and only if the 'infinite sum'...

... converges

Kind regards
