Consider &nbsp;&nbsp;&nbsp; '''n = -0.8'''&nbsp;&nbsp;&nbsp;  then &nbsp;&nbsp;&nbsp;  '''=ACOS(0.8)'''&nbsp;&nbsp;&nbsp; gives &nbsp;&nbsp;&nbsp;'''0.64350110879''' <br/>

Consider &nbsp;&nbsp;&nbsp; '''x = -0.8'''&nbsp;&nbsp;&nbsp;  then &nbsp;&nbsp;&nbsp;  '''=ACOS(0.8)'''&nbsp;&nbsp;&nbsp; gives &nbsp;&nbsp;&nbsp;'''0.64350110879''' <br/>

*This function is the inverse function of cos in trignometry.

*This function is the inverse function of COS in trignometry.

*Also it is called as cyclometric function.  

*Also it is called as Cyclometric function.  

*ACOS is described as arcCOS and denoted by <math>cos^-1</math> (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)
