Details
- Mathematical function, suitable for both symbolic and numerical manipulation.
- All results are given in radians.
- For real
outside the interval 
to 
, the results are always in the range 
to 
, excluding 
. - For certain special arguments, ArcSec automatically evaluates to exact values.
- ArcSec can be evaluated to arbitrary numerical precision.
- ArcSec automatically threads over lists.
- ArcSec[z] has a branch cut discontinuity in the complex
plane running from 
to 
.
