Bugs item #541353, was opened at 2002-04-08 23:19 You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=104933&aid=541353&group_id=4933 Category: None Group: None Status: Open Resolution: None Priority: 5 Submitted By: David Billinghurst (billingd) Assigned to: Nobody/Anonymous (nobody) Summary: del() not documented? Initial Comment: I couldn't find any documentation on del(), but as a wild guess I tried: (C1) U: 'diff(U,S)*S + 'diff(U,V)*V; dU dU (D1) -- V + S -- dV dS (C2) diff(U); dU dU (D2) -- DEL(V) + -- DEL(S) dV dS which seems OK. ---------------------------------------------------------------------- >Comment By: Raymond Toy (rtoy) Date: 2002-06-25 10:45 Message: Logged In: YES user_id=28849 Any suggestions on what to say? I was going to say something like: DEL(var) is the differential of var. So DIFF(F(X)) is DIFF(F(X),X)*DEL(X). Maybe add a couple of examples as well. How about that? ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=104933&aid=541353&group_id=4933 |

Examples are always good. ---------------------------------------------------------------------- Comment By: Raymond Toy (rtoy) Date: 2002-06-26 00:45 Message: Logged In: YES user_id=28849 Any suggestions on what to say?
