This activity shows how the convergence point of the Riemann zeta (s) function varies as the value of the real part of (s) in the range 0 < a <1.[br][br]To find out more, you can read an article of mine published on zenodo.org[br][br]http://doi.org/10.5281/zenodo.7015290[br][br]Thanks to GeoGebra's zeta(x) function I added the convergence point (green) of the Riemann zeta function; calculated according to the values (a) controlled by the slider and b=14.134i.
