Re: Zeroes of Zeta function


Plot[Abs[Zeta[1/2+I*y]],{y,0,50},ImageSize->500];

zeroes=y/.FindRoot[Zeta[1/2+I*y]==0, {y, #}]&/@
      {15,21,25,30,33,38,41,43,48,50}//Chop

{14.1347,21.022,25.0109,30.4249,32.9351,37.5862,40.9187,43.3271,48.0052,49.\

Zeta[1/2+I*zeroes]//Chop

{0,0,0,0,0,0,0,0,0,0}
