`atanh`

Computes the principal inverse hyperbolic tangent.

atanh evaluates supported numeric and complex arguments using the principal logarithmic form. Symbolic arguments remain as atanh(x) when no simplification applies.

Examples

These examples use Nerdamer Notation.

Evaluate the origin.

atanh(0)
// → 0

Keep a symbolic inverse hyperbolic tangent.

atanh(x)
