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 |
