* Where x is the COS of the angle and is from -1 to 1.

* Where x is the angle in radians and it is from -1 to 1.

* By default the result obtained will be in Radians

* By default calci use Radians as angle

*Calci returns the arcCOS (inverse Cos) of a number. Output is the angle in radians.

*Calci returns the arcCOS (inverse Cos) of a number. Output is the angle in radians.

*The number can be a single value or any number of values.

*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.  

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