Consider '''x = 90''' then '''=COS(RADIANS(90))''' gives '''0''' <br/>
Consider '''x = 90''' then '''=COS(RADIANS(90))''' gives '''0''' <br/>
The above function gives the Cosine of 'x' in Degree.<br/>

*By default, Calci takes the angle in Radians.
* To convert Radians to Degrees multiply with 180/PI() or we have to use the Radians function COS(RADIANS(x)) or DCOS(x).
