This function gives the cosine of 'x'.<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.
