* where '''x''' is the angle in Degrees
* '''Number''' is the angle in Degrees.
**DSEC(),returns the double-precision secant of the given angle
[[Manuals/calci/SEC| SEC]] can be used if the angle is in Radians.<br/>

==Description==
==Description==
*This function is used to obtain the Secant value of 'x' in degrees.<br/>
*This function is used to obtain the Secant value of any Number in degrees.
*It is the reciprocal of COS function i.e, '''SEC(x)''' = '''1 / COS(x)'''.<br/>
*It is the reciprocal of COS function i.e, '''SEC(x)''' = '''1 / COS(x)'''.Here x is any Number.
*In a right angled triangle '''SEC(x) = Hypotenuse / Adjacent side'''.<br/>
*In a right angled triangle '''SEC(x) = Hypotenuse / Adjacent side'''.<br/>
*To obtain the value in Radians multiply with PI()/180 or use SEC function SEC(x)
*To obtain the value in Radians multiply with PI()/180 or use SEC function SEC(x)

'''DSEC(x)'''
'''DSEC(Number)'''
*'''x ''' is the angle in degrees.
*'''Number ''' is the angle in degrees.
* SEC(-x)=-SEC(x)
* SEC(-x)=-SEC(x)
* Result shows DSEC(abc)= NAN
* Result shows DSEC(abc)= NAN
