Funktionsnavn:

ARCTAN2

Kategori:

Matematisk

Resume:

Returnerer vinklen (i radianer) mellem x-aksen og en linje fra nulpunktet (tallet X | tallet Y). Denne funktion beregner principalværdien.

Syntaks:

ARCTAN2(Number X; Number Y)

Returnerer:

ATAN2 returnerer vinklen (i radianer) mellem x-aksen og en linje fra nulpunktet til punktet ( tallet X | tallet Y). Vinklen returneres mellem -PI og PI, dvs. [-π,π].

If the function returns a positive angle it represents a counterclockwise angle from the x-axis, while a negative result represents a clockwise angle.

Argumenter:

Tallet X er værdien af ordinaten (x).

Tallet Y er værdien af koordinanten (y).

Tallet X og tallet Y kan begge være 0, hvortil funktionen returnerer 0.

  • If Number X and Number Y are both equal to 0, then ARCTAN2 returns the value 0.

Yderligere oplysninger:

The following illustration shows the geometry used by ARCTAN2 (φ is the angle calculated).

  • Til at returnere en vinkel i grader bruger du funktionen GRADER.
  • Hvis funktionen returnerer en positiv vinkel, repræsenterer det en vinkel imod uret fra x-aksen, mens et negativt resultat repræsenterer en vinkel med uret.

Eksempler:

=ARCTAN2(-5; 9) Here the function calculates the angle (in radians) between the x-axis and a line from the origin to the point (-5, 9). 2,07789483118723
=GRADER(ARCTAN2(12,3; 12,3)) Here the function calculates the angle (in degrees) between the x-axis and a line from the origin to the point (12.3, 12.3). 45
=ARCTAN2(D1; D2) where cells D1 and D2 both contain the value 0. Here the function returns 0. 0
=ARCTAN2(-5; -3)*180/PI() Here the function calculates the angle (in degrees) between the x-axis and a line from the origin to the point (-5, -3). -149,036243467926
GRADER(ARCTAN2(-8; 5)) Here the function calculates the angle (in degrees) between the x-axis and a line from the origin to the point (-8, 5). 147,994616791916
