Consider &nbsp;&nbsp;&nbsp; '''x = 90'''&nbsp;&nbsp;&nbsp;  then &nbsp;&nbsp;&nbsp;  '''=COS(RADIANS(90))'''&nbsp;&nbsp;&nbsp; gives &nbsp;&nbsp;&nbsp;'''0''' <br/>

Consider &nbsp;&nbsp;&nbsp; '''x = 90'''&nbsp;&nbsp;&nbsp;  then &nbsp;&nbsp;&nbsp;  '''=COS(RADIANS(90))'''&nbsp;&nbsp;&nbsp; gives &nbsp;&nbsp;&nbsp;'''0''' <br/>

This function gives the cosine of 'x' in Degree.<br/>

The above function gives the Cosine of 'x' in Degree.<br/>

In a right angled triangle,     '''COS'''='''adjacent'''/'''hypotenuse'''.<br/>

In a right angled triangle,&nbsp;&nbsp;  '''COS'''='''Adjacent'''/'''Hypotenuse'''.<br/>

It will give the value in radians.To convert that in degrees  multiply with PI()/180 or we have to use the radians function.

By default, Calci give the values in Radians. To convert Radians to degrees  multiply with PI()/180 or we have to use the Radians function.

* COS function determines the sine of the given angle. <br/>

* COS function determines the Cosine of the given angle. <br/>

The following example shows how COS is applied to an array of numbers containing numbers 1..10.
