ACOS(n)

Calci returns the arcCOS (inverse Cos) of a number. Output is the angle in radians.
To convert arcCOS to the degrees, multiply it by 180/PI.
The number can be a single value or any number of values.

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

Consider n = -0.8 then =ACOS(0.8) gives 0.64350110879

This function is the inverse function of cos in trignometry.
Also it is called as cyclometric function.
ACOS is described as arcCOS and denoted by $cos^{-}1$ (n).In ACOS(X) ,x value should be with in -1&1.Here x is in radians. To convert a degree value to radian, multiply 'x' with PI()/180 or use the radians function RADIANS(X)
