Examples for
Zeta Functions
Zeta functions are a family of special functions defined through a Dirichlet series. The most famous example is the Riemann zeta function. Wolfram|Alpha can compute values for multiple variants of zeta functions as well as help you explore other functionalities, such as visualization and series expansion.
Riemann Zeta Function
Compute the properties for the Riemann zeta function or get a Riemann zeta function calculator.
Compute the exact values of the zeta function:
Numerically evaluate zeta near a nontrivial zero:
Plot the zeta function on the critical line:
Find series representations of the zeta function:

Riemann–Siegel Functions
Visualize or compute the Riemann–Siegel Z function and the Riemann–Siegel theta function.
Plot the Riemann–Siegel functions:
Hurwitz Functions
Generalize the Riemann zeta function to the Hurwitz zeta function and further to the Lerch transcendent.
