[QUOTE="bhobba, post: 6023106, member: 366323"] Yes - but unless you want to get into non-standard analysis infinitesimals are a load of the proverbial, although used every now and then when speaking informally. I do it but shouldn't really. There is no way to understand it properly unless you study the references in my link. Start with Distribution Theory. Thanks Bill [/QUOTE]
