Hi! There seems to be a minor error in the description of D. Derivative The line
(*/\ VD y);(sin x);(sin D x);(sin D D x) should read (*/\ VD x);(sin x);(sin D x);(sin D D x) That is, the y should be an x. Thanks! Bo. ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
