Arc Secant
The arc secant of a real number x is a real number with a secant of x.
The argument x of the arc secant relation is a real number between [latex]-\infty[/latex] and [latex]+\infty[/latex].
The relation defined by y = arcsec(x) is not a function.
Notation
The symbol used for the arc secant of a number x is “arcsec(x)” which is generally read as “arc secant of x.”Examples
In the sexagesimal system of measuring angles, we have: arcsec(2) = 60 arcsec(2) = 360n ± 60 where n is an integer.- arcsec(2) = 60
- arcsec(2) = 360n ± 60 where n n is an integer.
