Inverse lemniscate functions

ID: inverse-lemniscate-functions

The inverse lemniscate functions are mathematical functions that are related to the geometrical shape known as the lemniscate, which resembles a figure-eight or an infinity symbol (∞). The most commonly referenced lemniscate is the lemniscate of Bernoulli, which is defined by the equation: \[ (x^2 + y^2)^2 = a^2 (x^2 - y^2) \] for some positive constant \(a\).
