*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)
*DCOTAN returns NaN if 'x' is not real
*DSEC returns NaN if 'x' is not real
The angle can be a single value or any complex array of values.
The angle can be a single value or any complex array of values.
The following example shows how COTAN is applied to an array of numbers containing numbers 1..10.
The following example shows how DSEC is applied to an array of numbers containing numbers 1..10.
*Type =1..10@DSEC in Calci
*Type =1..10@DSEC in Calci
*Type =1..10@DSEC or 1..10@DSEC in ZOS
*Type =1..10@DSEC or 1..10@DSEC in ZOS
