* 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
