ARCCOT

Matematisk

## Resume:

Returnerer den inverse cotangens (arcus-cotangens) af et tal. Denne funktion beregner principalværdien.

## Syntaks:

ARCCOT(Number)

## Returnerer:

Denne funktion returnerer den inverse trigonometriske cotangens af tallet, der er vinklen (i radianer), hvis cosinus er tallet. Den returnerede vinkel ligger mellem 0 og PI, dvs. [0,π].

## Argumenter:

Tallet er det reelle tal eller en reference til en celle, der indeholder tallet, hvis inverse trigonometriske cotangent-værdi skal beregnes.

• If Number is non-numeric, then ARCCOT reports a #VÆRDI! error.

## Yderligere oplysninger:

• Alternativt multiplicerer 180/PI() for at konvertere resultatet fra radianer til grader.

Funktionen ARCCOT

## Eksempler:

Formula Description Returns
=ARCCOT(−1) Inverse trigonometric cotangent of -1. 2,35619449019234 (3π/4)
=ARCCOT(0,5) Inverse trigonometric cotangent of 0.5. 1,10714871779409
=GRADER(ARCCOT(0,5)) Inverse trigonometric cotangent of 0.5, converted to degrees. 63,434948822922
=ARCCOT(0,5)*180/PI() Inverse trigonometric cotangent of 0.5, converted to degrees. 63,434948822922
=GRADER(ARCCOT(COT(RADIANER(60))) An angle of 60° is converted to radians, its cotangent is taken, then the inverse cotangent of that value is calculated, and finally the result is converted back to degrees. 60
