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.

SendCalc 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.
