Consider &nbsp;&nbsp;&nbsp; '''x = 90'''&nbsp;&nbsp;&nbsp;  then &nbsp;&nbsp;&nbsp;  '''=COS(RADIANS(90))'''&nbsp;&nbsp;&nbsp; gives &nbsp;&nbsp;&nbsp;'''1''' <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'.<br/>

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

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

In a right angled triangle,'''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.
