Birkhoff Visualized

y \mapsto y \pm \sqrt{y^{2} - 1}

/// Inverse of

z \mapsto \frac{1}{2} (z + \frac{1}{z})

, the Birkhoff Regularization, adjusted order of sqrt-results.

Draw on the left side, get the preimage on the right side.

Prototype for visualizing stuff for my master thesis, see the repository for source code.
