- arctan
- (mathematics, sometimes proscribed) Alternative form of ar- used to form the names of inverse hyperbolic trigonometric functions, and the symbols for these functions.
Usage notes
The use of arc- with hyperbolic functions is sometimes discouraged, as the term arc implies a circular angle. The forms with ar- (derived from hyperbolic area) are more common anyway due to being shorter.
