+NAME
+    cot - trigonometric cotangent
+
+SYNOPSIS
+    cot(x [,eps])
+
+TYPES
+    x		nonzero real
+    acc		nonzero real, defaults to epsilon()
+
+    return	real
+
+DESCRIPTION
+    Calculate the cotangent of x to a multiple of eps, with error less
+    in absolute value than .75 * eps.
+
+EXAMPLE
+    > print cot(1, 1e-5), cot(1, 1e-10), cot(1, 1e-15), cot(1, 1e-20)
