Contents: Description, Arguments, Usage, Examples, Sub-Functions, Related Functions, Source Supported Under Version: > 1.11 Current .dvrc Version: 1.29 Description Computes the trigonometric secant of the input value. Arguments and Return Values Parameters: An array of any numeric data type or organization containing the values of angles in radians. Return Value: A float array of the same organization as the input containing the secant of the input. Usage Syntax: sec(x) 'x' is any numeric array This function just uses sec(x) = 1/cos(x) Secant is undefined (infinite) for x = π/2 + n*π for any integer n; this function displays a divide by zero warning and returns zero in those cases Return format is double if input is double; float otherwise When sec() is entered without any arguments, it prints its description, as shown below.
