Consider '''n = 90''' then '''=COS(RADIANS(90))''' gives '''1''' <br/>

* COS function determines the sine of the given angle.
This fuction gives the cosine of 'x'.
In a right angled triangle,COS=adjacent/hypotenuse.
It will give the value in radians.To convert that in degrees multiply with PI()/180 or we have to use the radians function.
* COS function determines the sine of the given angle. <br/>
The following example shows how COS is applied to an array of numbers containing numbers 1..10.
