u'(1-epsilon(u')^2)=-y
uo(1)=0 u1(1)=0
I need solve this problem with mathematica.

Is this homework? In any case, you will probably have to give more details.
 
No its my thesis.İm mechanical engineer.İm doing master on fluid mechanics
 
Can you give even more details? While I may not be the one to be able to help you here, I think that not knowing what ε, u0, u1, etc. represent is going to make it hard for anyone to give you advice.

I need solve this problem with mathematica.
 
I solved the momentum equation of the fluid by perturbation method. I need to encode and validate the solution with mathematica. I used direct expansion in the solution of the perturbation. I want information about the code.
 
Which parameters do you know, what is a function of what, what are uo and u1?

You can’t expect help if you don’t explain the problem sufficiently for others to understand it.

How to my shares data of the problem ?
 
Can you use to mathematica?
 
So, you solved the problem by hand, but you have to do it in MMA, for your thesis? Is that correct? I know a little MMA, and I'm willing to look into it, but I can't read the photos of your solution, so I'm going to need some more information. Reading your original post, it looks like you are working with 4 functions - u, u0, u1 and epsilon. Is that right? It seems a little peculiar to me. A more explicit problem statement would be helpful.

Thanks.Are you know perturbation method?
Yes its required for my thesis.
