+### Usage
+
+```c
+#include "stdlib/math/base/special/sin.h"
+```
+
+#### stdlib_base_sin( x )
+
+Computes the [sine][sine] of a `number` (in radians).
+
+```c
+double y = stdlib_base_sin( 3.141592653589793 / 2.0 );
+// returns ~1.0
+```
+
+The function accepts the following arguments:
+
+- **x**: `[in] double` input value.
+
+```c
+double stdlib_base_sin( const double x );
