+
+## Usage
+
+```javascript
+var csc = require( '@stdlib/math/base/special/csc' );
+```
+
+#### csc( x )
+
+Computes the [cosecant][cosecant] of a `number` (in radians).
+
+```javascript
+var v = csc( 0.0 );
+// returns ~Infinity
+
+v = csc( 3.141592653589793/2.0 );
+// returns ~1.0
+
+v = csc( -3.141592653589793/6.0 );
+// returns ~-2.0
+```
