I really don't know how u^\prime.\dfrac{\partial u^\prime}{\parital x} and v^\prime.\dfrac{\partial u^\prime}{\parital x} are gone at the 2nd equation, in (1)? I'll very happy if you explain it to me. Thank you so much.Anonymoushttps://www.blogger.com/profile/11376210685409492008noreply@blogger.comtag:blogger.com,1999:blog-1308139960516080412.post-64116562223881931952016-05-22T09:41:38.075-05:002016-05-22T09:41:38.075-05:00Thanks a ton, Christopher.Thanks a ton, Christopher.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-1308139960516080412.post-32901575134981073732015-12-07T11:01:27.257-06:002015-12-07T11:01:27.257-06:00Hello Christopher, thanks a lot.
