The angle can be a single value or any complex array of values.
The angle can be a single value or any complex array of values.
For example COS(1..100) can give an array of the results, which is the COS value for each of the elements in the array. The array could be of any values either '+' or '-' like 1..5@COS or (-5)..(-1)@COS.

*By default, Calci takes the angle in Radians.
*By default, Calci takes the angle in Radians.
*COS(Radians(90))= 6.123031769111886e-17. So for calculation we consider COS(Radians(90))=0
* To convert Radians to Degrees multiply with 180/PI() or we have to use the Radians function COS(RADIANS(x)) or DCOS(x).<br/>
