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

+
+LIMITS
+    unlike sin and cos, x must be real
