What is the asech or inverse hyperbolic secant?
Inverse hyperbolic secant is the inverse of the hyperbolic secant, which is the reciprocal of the of the hyperbolic cosine. It can also be written using the natural logarithm:
Arcsech as a formula
Inverse hyperbolic cosecant is often written as arcsech, but usually abbreviated as "asech" or "arsech", as in the following equation:
arcsech(y) = asech(y) = arsech(y)
Where it is the inverse of hyperbolic secant, or:
