# Euler's derivation of Riemann Zeta Function for even integers

So Euler derived the analytic expression for the even integers of the Riemann Zeta Function. I was wondering if there is a link to his derivation somewhere?

Also, is there anyone else who used a different method to get the same answer as Euler?

Thank you
