    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(Number)

    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.

    Další detaily:

    • 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.

    Vzorec Popis Vrátí
    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
