+### Usage
+
+```c
+#include "stdlib/math/base/special/asec.h"
+```
+
+#### stdlib_base_asec( x )
+
+Computes the [inverse (arc) secant][arcsecant] of `x`.
+
+```c
+double out = stdlib_base_asec( 2.0 );
+// returns ~1.0472
+```
+
+The function accepts the following arguments:
+
+-   **x**: `[in] double` input value.
+
+```c
+double stdlib_base_asec( const double x );
+```
