gives the Ramanujan tau theta function theta(t).
  • Mathematical function, suitable for both symbolic and numerical manipulation.
  • Apart from a sign, theta(t) gives the phase of the Ramanujan L-function L(6+i​t).
  • For certain special arguments, RamanujanTauTheta automatically evaluates to exact values.
