Arccsch

The inverse hyperbolic cosecant function

fun arccsch(number)

Parameters

• number: A dimensionless number value

Discussion

arccsch is the inverse of csch so if arccsch(number) == x then csch(x) == number. The returned number is in terms of radians:

arccsch(1)
arccsch(.5)

0.88 rad
1.44 rad

arccsch is valid for all numbers except 0.
