Die acosh () funksie bereken Die omgekeerde hiperbolies kosinus van x. Wat is Die waarde wie se hiperbolies kosinus is x. As x is minder as 1. 0, acosh () gee terug not- a- number (Nan) en fout- nr is stel.
The ACOSH() function calculates the inverse hyperbolic cosine of x. That is the value whose hyperbolic cosine is x. If x is less than 1.0, acosh() returns not-a-number (NaN) and errno is set.
