Let's suppose we have a Non-linear operator (supposing is self-adjoint and all that) so:(adsbygoogle = window.adsbygoogle || []).push({});

[tex] cos(y'')+(y')^{2}y+xy=g(x) [/tex] with the boundary conditions for some a and be real

y(a)=0 and y(a)+2y(b)=0 then the "superposition principle" can't be applied so how the hell do you solve it

By the way, does "Non-linear Fourier Analysis or Harmonic analysis2 exists?? :surprised :surprised
