+<h2>Description</h2>
+
+<p>The 'cos' function returns the cosine of the 'expr'. The 'expr' is
+in radians.</p>
+
+<h2>Examples</h2>
+
+<pre class="example">
+(cos 0.0)            <font color="#008844">; returns 1</font>
+(cos (/ 3.14159 2))  <font color="#008844">; returns 1.32679e-06 (almost 0)</font>
+(cos .5)             <font color="#008844">; returns 0.877583</font>
+(cos 0)              <font color="#008844">; error: bad integer operation</font>
+(cos 1.)             <font color="#008844">; error: bad integer operation</font>
