i Need help please

Solve the following differential equation:x((d^3y)/dx^3) - ((dy)/dx)^4+y=0

can anyone teach me this?

[Jan]

Numerically or symbolically? What have you tried so far?

[Saba Bukhnikashvili]

numerically, i have tried dsolve but i do not understand it

[Torsten]

What are your boundary conditions ?

[Saba Bukhnikashvili]

there are no boundary conditions

[Torsten]

Then - since you won't get an analytical solution for this equation using dsolve - it's impossible to get a solution for your ODE.

You need 3 boundary conditions to solve the above equation numerically.

Thank you for the information
