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 .
