Funktionsnavn:

TANH

Kategori:

Matematisk

Resume:

Returnerer den hyperbolske tangens af et tal.

Syntaks:

TANH(Number)

Returnerer:

Returnerer den hyperbolske tangens af tallet. Den resulterende værdi er mellem -1 og +1, dvs. [-1,+1].

Argumenter:

Tallet er det reelle tal eller en reference til en celle, der indeholder det tal, hvis hyperbolske tangens-værdi skal beregnes.

  • If Number is non-numeric, then TANH reports a #VALUE! error.
