Returns the arccosine of a number.
Ta funkcja działa w Arkuszach Google tak samo jak w Excelu — ta sama składnia i argumenty.
ACOS(number)The ACOS function calculates the angle whose cosine is the specified number. The returned angle is given in radians in the range 0 to pi.
=ACOS(0.5)Wynik: 1.047197551
Returns the arccosine of 0.5 in radians, which is pi/3.
=ACOS(-1)Wynik: 3.141592654
Returns the arccosine of -1, which is equal to pi.
Excel will return the #NUM! error because the cosine of an angle cannot be outside this range.
You can use the formula =DEGREES(ACOS(number)).
