Arcsine VS Arcsinh

David Byrd

For what it's worth.

Functions Sin and Inverse sin or arcsin are trig functions based on the circle.

Functions sinch and arcsinch are not trig functions as they are based on the hyperbola and are hyperbolic functions

The Functions listed in the GHS include an arcsinh function but not an arcsin function.

The arcsinh function is pronounced arc cinch
