<div style="font-size:30px">'''DCOS(x)'''</div><br/>
* where '''x''' is the angle in Radians
* by default Calci use Radian as angle
[[Manuals/calci/COS| COS]] can be used if the angle is in Radians.
'''DCOS'''(n)
==Description==
*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/>
*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)
*DSEC returns NaN if 'x' is not real
The angle can be a single value or any complex array of values.
The following example shows how DSEC is applied to an array of numbers containing numbers 1..10.
*Type =1..10@DCOS in Calci
*Type =1..10@DCOS or 1..10@DCOS in ZOS
