WeierstrassEta2

WeierstrassEta2[{g2, g3}] gives the value η₂ of the Weierstrass zeta function ζ at the half-period ω₂(g₂, g₃).

Examples

Compute eta2 for specific invariants:

WeierstrassEta2[{4, 5}]

Relation to half-periods:

{g2, g3} = {1, 0};
eta2 = WeierstrassEta2[{g2, g3}];
omega2 = WeierstrassHalfPeriods[{g2, g3}][[2]]

Numerical value:

N[WeierstrassEta2[{1, 2}]]
