sec()
µ key
Note: The argument is interpreted as a
degree, gradian or radian angle, according
to the current angle mode setting. You can
use °,
G
, or
r
to override the angle mode
temporarily.
sec⁻¹()
µ key
sec⁻¹(Expr1) ⇒ expression
sec⁻¹(List1) ⇒ list
Returns the angle whose secant is Expr1 or
returns a list containing the inverse secants
of each element of List1.
Note: The result is returned as a degree,
gradian, or radian angle, according to the
current angle mode setting.
Note: You can insert this function from the
keyboard by typing arcsec(...).

sech(Expr1) ⇒ expression
sech(List1) ⇒ list
Returns the hyperbolic secant of Expr1 or
returns a list containing the hyperbolic
secants of the List1 elements.
sech⁻¹()
Catalog >
sech⁻¹(Expr1) ⇒ expression
sech⁻¹(List1) ⇒ list
Returns the inverse hyperbolic secant of
Expr1 or returns a list containing the
inverse hyperbolic secants of each element
of List1.
Note: You can insert this function from the
keyboard by typing arcsech(...).
