*This function is used to obtain the COS value of 'x' in Degrees.<br/>

*It is the reciprocal of SEC function i.e,'''COS(x)''' = '''1 / SEC(x)'''.<br/>

*It is the reciprocal of SEC function i.e, '''COS(x)''' = '''1 / SEC(x)'''.<br/>

*In a right angled triangle '''COS(x) = Adjacent side / Hypotenuse'''.<br/>

*In a right angled triangle '''COS(x) = Adjacent side / Hypotenuse'''.<br/>

*To obtain the value in Radians multiply with PI()/180 or use COS function COS(X)
