Returns the angle whose secant is
expression1
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.
In Degree angle mode:

var
Sends variable
var
to the link port, where another
unit linked to that port can receive the variable
value. The receiving unit must be on the Home
screen or must execute GetCalc from a program.
If you send from a TI-89, TI-92 Plus, or
Voyage™ 200 to a TI-92, an error occurs if the
TI-92 executes GetCalc from a program. In this
case, the sending unit must use SendChat
instead.
