i am tryin to solve this (sorry i am not good writin it in latex):
d*y''(x)+a*y(x)*y''(x)+a*(y'(x))^2-b*x-c*y(x)-f*(y(x))^2-g=0
as i said before, d,a,c,b,g are arbitrary constants...
Am i writing this wrong, or there is not analytical solutions?

Hello! I am new to Mathematica and i tried to solve a non linear second order ode... The result is that nothing happens... I mean that i get as output the same line as i write in input.. For example, my problem is: (thats what i get)
In[33]:= DSolve[ g - b x - c...
Hello... My main problem is to find the Green's function of this pde:
\frac{∂T(x,t)}{∂t}=\frac{∂}{∂x}(D(x)\frac{∂T(x,t)}{∂x}) .
This is the well-known diffusion equation, but here, the diffusion coefficient is coordinate-dependent.
My main focus is to find the Green's function, but i know...
