WeierstrassInvariantG3
WeierstrassInvariantG3[{ω,ω′}]
gives the invariant 
for the Weierstrass elliptic functions corresponding to the half‐periods {ω,ω′}.
Details
- Mathematical function, suitable for both symbolic and numerical manipulation.
- WeierstrassInvariantG3 gives the second invariant from the pair given by WeierstrassInvariants.
- For certain special arguments, WeierstrassInvariantG3 automatically evaluates to exact values.
- WeierstrassInvariantG3 can be evaluated to arbitrary numerical precision.
- WeierstrassInvariantG3 can be used with CenteredInterval objects. »
