WeierstrassInvariantG2
WeierstrassInvariantG2[{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.
- WeierstrassInvariantG2 gives the first invariant from the pair given by WeierstrassInvariants.
- For certain special arguments, WeierstrassInvariantG2 automatically evaluates to exact values.
- WeierstrassInvariantG2 can be evaluated to arbitrary numerical precision.
- WeierstrassInvariantG2 can be used with CenteredInterval objects. »
