Inverse Hyperbolic Sine: Also known as
The principal branch of the inverse hyperbolic sine is also known as the area hyperbolic sine, as it can be used, among other things, for evaluating areas of regions bounded by hyperbolas.

Some sources refer to it as hyperbolic arcsine, but this is strictly a misnomer, as there is nothing arc related about an inverse hyperbolic sine.
