Explanation for the next steps of chaplygin dipole @JuanSimões, ok, I will read about that. and you answered about that: "I think v is the two first elements of (2.2) [thanks to your link]. am I right?" thank you very much!! you don't know how much you help me to understand it! |

Explanation for the next steps of chaplygin dipole @JuanSimões, wow, the first step is by definition! thanks! (2.3) is a choice (thank you again), and I guess (2.4) is also, right? so (2.5) is a derivative of which v (once by r and once by theta)? I think v is the two first elements of (2.2) [thanks to your link]. am I right? |

Explanation for the next steps of chaplygin dipole @JuanSimões, thank you.. to be honest I didn't understand the step between (1.2) to (2.2). and why he chose the function of Psi and this Omega in (2.3)? thank you very much! |

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

Bernoulli integral (conservation of energy) thank you Tom! I didn't try to prove that.. what's about what I wrote in the topic, under the title: First solution ? |
