ACOS(Number)

is any value and it is varying from -1 to 1.
- ACOS() returns the arccosine of a number.

For example, ACOS(0.5,(-0.2),1) gives the arcCOS or inverseCOS values for each element.

Consider x = 0.8 then =ACOS(0.8) gives 0.64350110879
Also it is called as Cyclometric function.
ACOS is described as arcCOS of a given number and denoted by $cos^{-1}(x)$ .
In ACOS(x), x value should be between -1 & 1.
To find the angle in degrees, multiply the result angle with 180/PI(), or use DEGREES function.

For example ACOS(0.5)*180/PI() or DEGREES(ACOS(0.5)) gives 60

 *Calci returns the value of arccosine (inverse cosine) in Radians.
 *The number can be a single value or any number of values.
