comment Bernoulli integral (conservation of energy)
ok, so my last question: does first solution contain the full solution? thank you for all your comments.

thank you Tom! I didn't try to prove that.. what's about what I wrote in the topic, under the title: First solution ?

comment Bernoulli integral (conservation of energy)
thank you very much Tom! I think I will show them the both solutions, so I have one proof (of you). about the second proof: do you have a link with a solution of rewriting Euler equations to form (2.13)? and then the second solution will be the rewriting Euler equations to form (2.13) and after that I will write (2.14)-(2.19). BTW, what's about (2.1)-(2.12)? I don't need this? about your question, The lecturer wants me to lecture about this topic.. so I will have to learn the both solutions (I will learn it by myself when I get them).. thank you very very much!
