I was wondering if someone can show me or point me to a worked out example using integration by parts for more than one variable (as used in relation to pde's, for example). While I took pdes and calc 3, its been awhile and I dont know if I ever understood how to work out a concrete example regardless. When I look on wikipedia,say, they reference replacing certain parts using 'green's identities'; but I dont understand green's identities either. SO in conclusion I can not find a good concrete example for doing this intergration by parts involving more than one variable and relating it to all that green stuff.(adsbygoogle = window.adsbygoogle || []).push({});
