Název funkce:

ATAN

Kategorie:

Matematické

Shrnutí:

Vrátí inverzní trigonometrický tangens (arctangent nebo arctan) čísla. Vrácená hodnota je hlavní hodnota a leží v rozmezí (-π/2, π/2) radiánů.

Syntaxe:

ATAN(Číslo)

Vrátí:

Vrátí číslo v rozsahu (-π/2, π/2) inverzní tangens Čísla v radiánech.

Argumenty:

Number is a real number, or a reference to a cell containing that number, whose inverse trigonometric tangent is to be calculated.

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

Additional details:

  • To return the angle in degrees, use the DEGREES function.
  • Alternatively multiply by 180/PI() to convert the result from radians to degrees.

The figure below illustrates the function ATAN.

Examples:

Template:Calc-Formula/cs Template:Calc-Description/cs Template:Calc-Returns/cs
=ATAN(-1) Inverse trigonometric tangent of -1. -0,785398163397448 (-π/4)
=ATAN(D1) where cell D1 contains the number 0.5. Inverse trigonometric tangent of 0.5. 0,463647609000806
=DEGREES(ATAN(0.5)) Inverse trigonometric tangent of 0.5, converted to degrees. 26,565051177078
=ATAN(-0.5)*180/PI() Inverse trigonometric tangent of -0.5, converted to degrees. -26,565051177078
=DEGREES(ATAN(TAN(RADIANS(60))) An angle of 60° is converted to radians, its tangent is taken, then the inverse tangent of that value is calculated, and finally the result is converted back to degrees. 60
