ACOS(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

This function is the inverse function of COS in trigonometry.
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
