## Scope(7)

Evaluate to arbitrary precision:

The precision of the output tracks the precision of the input:

Evaluate symbolically for the equianharmonic case:

Evaluate symbolically for the lemniscatic case:

WeierstrassE3 has both singularities and discontinuities:

WeierstrassE3 is neither non-negative nor non-positive:

It is inherently complex:

WeierstrassE3 is neither convex nor concave:

## Applications(1)

Find the elliptic modulus m corresponding to an elliptic curve specified by its Weierstrass invariants:

Compute the modulus using an alternative formula:

## Properties & Relations(3)

Values of WeierstrassP at its half-periods are the roots of the defining polynomial:

Values of WeierstrassP at its half-periods are not linearly independent:

This identity holds for all arguments:

The elementary symmetric polynomials evaluated at the values of WeierstrassP at half-periods yield WeierstrassInvariants (the Vieta relations):
