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