Riemann Zeta Function
This calculator finds the numerical value of the Riemann zeta function \[ \zeta(s)=\sum_{s=1}^\infty \frac{1}{n^s} = \frac{1}{1^s}+\frac{1}{2^s}+\frac{1}{3^s}+\cdots \] where $s$ is a real or complex number. If $s$ is a complex number, it must be in the form a+b*i without space among them.
