Arccoth

The inverse hyperbolic cotangent function

fun arccoth(number)

Parameters

• number: A dimensionless number value

Discussion

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

arccoth(1.1)
arccoth(2)

1.52 rad
0.55 rad

arccoth is valid where number > 1 or number < -1
