SUMMARY

The discussion focuses on solving a fourth-order nonlinear ordinary differential equation (ODE) represented as a*y'''' + y'''y - y''y' = 0, with specified boundary conditions y(h/2) = V1, y(-h/2) = V2, y'(h/2) = 0, and y'(-h/2) = 0. The equation can be reduced to a third-order ODE, a y''' + y''y - y'^2 = C, through integration. However, the consensus is that exact solutions for nonlinear differential equations are generally unattainable, necessitating numerical methods for resolution.

PREREQUISITES
  • Understanding of nonlinear ordinary differential equations (ODEs)

hello
I want to find exact solution of a nonlinear ode with its boundary conditions . the equation
and its b.cs are written below :

a*y''''+y''' y -y'' y' = 0 y(h/2)=V1 , y(-h/2)=V2 , y'(h/2)=0 , y'(-h/2)=0

where V1 , V2 , a and h are constant .

although with integerating from above equation , the order of ode reduce to 3 but the problem is until unsolveable .

after integrating from above equation we have : a y''' +y'' y -y'^2 =C
where C is constant .

In general, you won't be able to find exact solutions to non-linear diff.eqs; you'll need to solve it numerically.
