Homework Statement
Eulerian velocity: [tex]V_{1}=-z_{1}^{2}[/tex]
[tex]V_{1}=\frac{dz_{1}}{dt}[/tex]
[tex]z_{1}(t=0)=x_{1}[/tex]
This is supposed to become the Lagrangian velocity of:
[tex]z_{1}=\frac{x_{1}}{1+tx_{1}}[/tex]
I don't understand how to take the Eulerian velocity and transform it to Lagrangian.
Homework Equations
The Attempt at a Solution
[tex]\frac{dz_{1}}{dt}+z_{1}^{2}=0[/tex]
After this, I don't know how to take this and move forward.
I've been working the problem for a day, and I still can't get any closer. I can take Lagrangian and transform it to Eulerian, but I don't know how to do the reverse. TJ Chung's General Continuum Mechanics book is poorly developed for examples and proofs.
