arctanhvc
Arctanhvc is not a standard or widely used mathematical term. In conventional notation, arctanh denotes the inverse hyperbolic tangent function, defined for scalar inputs x with -1 < x < 1 by atanh(x) = 0.5 ln((1+x)/(1−x)). The addition of the suffix “vc” does not have an established universal meaning in mainstream references, so arctanhvc typically signals a nonstandard or context-specific construction.
In practice, when arctanhvc appears, it is commonly interpreted in one of two ways. One common interpretation
An alternative interpretation, when specified in a source, is that arctanhvc denotes a scalar function derived
Because arctanhvc is not standardized, readers should consult the original text or software documentation to determine
