G B Reid MIMechE, SIMarEST 76 Posted April 15 Report Share Posted April 15 (edited) Okay....this is a bit of a role reversal....I'm far more used to offering guidance and answers than asking the questions, but here it goes.... Can anyone give a reference to a good, easy-to-follow(!), text of Taylor and Binomial expansion of Differential equations? Specifically that used in "Variational Calculus". This is something I have covered in the dim and distant past...and as the saying goes..."it's not what you know, its what you think you know and don't realise you have forgotten!"...alas, it appears I have forgotten! I have some texts on the subject, but alas insufficient to clear my mental block! Many thanks to all!

DrD 839 Posted April 21 Report Share Posted April 21 I'm pretty familiar with variational methods, but I'm not quite clear about what you want. Can you cast your question in the context of a specific problem, perhaps? If not, shoot me a PM and we'll talk. DrD Quote Link to post Share on other sites
G B Reid MIMechE, SIMarEST 76 Posted August 12 Author Report Share Posted August 12 Hi DrD Thank you for offering to assist! I was undertaking a personal development course, and had not been supplied the "bridging material" that was essential for understanding. This lack of bridging manifested as difficulty in Taylor and Binomial expansions...but it turned out to be a lack of fundamental understanding of the subject which was addressed when the bridging materials were eventually supplied (six months after the start of the course!) I got a very good pass, but not the grade I would have got had I been supplied the full content in good time! C'est la vie! Thank you again Bruce Quote Link to post Share on other sites
DrD 839 Posted August 14 Report Share Posted August 14 Dear Bruce, As you well know, that's how things go at times. Better luck next time! DrD Quote Link to post Share on other sites
