WeierstrassZeta takes as a second argument the coefficients  of the equation of the elliptic curve under consideration (in Weierstrass normal form). If instead we know the periods of the curve, we start by using WeierstrassInvariants.

The Weierstrass zeta function satisfies the following quasiperiodicity condition: if  is any element of the lattice  generated by the periods  and  , then  for all  , where  is a constant depending on  . For  , we have  . Here is an example, with  :
