* Where x is the number and it is from -1 to 1.

* Where x is the number and it is varying from -1 to 1.

* By default calci use Radians as angle

* The value of ACOS(x) is in radians.

*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.

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

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

*In  ACOS(x), x value should be with in -1 & 1.

*In  ACOS(x), x value should be with in -1 & 1.

*To find the angle in degrees, multiply the result angle with 180/PI.

*To find the angle in degrees, multiply the result angle with 180/PI().

*DEGREES function can also be used.<br/>

*DEGREES function can also be used.<br/>

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

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