+NAME
+    acsc - inverse trigonometric cosecant
+
+SYNOPSIS
+    acsc(x [,eps])
+
+TYPES
+    x		real, with absolute value >= 1
+    eps		nonzero real, defaults to epsilon()
+
+    return	real
+
+DESCRIPTION
+    Returns the acsc of x to a multiple of eps with error less in
+    absolute value than .75 * eps.
+
+    v = acsc(x) is the number in [-pi/2, pi/2] for which csc(v) = x.
+
+EXAMPLE
+    > print acsc(2, 1e-5), acsc(2, 1e-10), acsc(2, 1e-15), acsc(2, 1e-20)

+
+LIMITS
+    unlike sin and cos, x must be real
+    abs(x) >= 1
+    eps > 0
