SIN

Matematisk

## Resume:

Returnerer sinus af den givne vinkel (i radianer).

SIN(Number)

## Returnerer:

Returnerer den (trigonometriske) sinus af tallet, vinklen i radianer. Den resulterende værdi ligger mellem -1 og 1, dvs. [-1,1].

## Argumenter:

Tallet er det reelle tal, eller en reference til en celle, der indeholder tallet, som er vinklen i radianer, hvis sinus-værdi skal beregnes.

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

## Yderligere oplysninger:

For at indsætte en vinkel i grader, multiplicerer du enten vinklen med PI()/180 eller bruger funktionen RADIANER til at konvertere vinklen til radianer.

The formula for the trigonometric sine of x is:

$\displaystyle{ \sin(x)~=~\sum_{n=0}^{\infty }\frac{(-1)^{n}}{(2n+1)!}~x^{2n+1} }$

GIFen herunder illustrerer funktionen SIN.

Funktionen SIN

## Eksempler:

Formel Beskrivelse Returnerer
=SIN(1) Trigonometric sine of 1 radian. 0,841470984807896
=SIN(D1) where cell D1 contains the number -0.5. Trigonometric sine of -½ radian. −0.479425538604203
=SIN(PI()/2) Trigonometric sine of π/2 radians. 1
=SIN(RADIANER(30)) Trigonometric sine of 30°, after first converting the angle from degrees to radians. 0,5
=GRADER(ARCSIN(SIN(RADIANER(60))) An angle of 60° is converted to radians, its sine is taken, then the inverse sine of that value is calculated, and finally the result is converted back to degrees. 60
