Hi,
i have a function of the form:

F(n)=a[n]*x[n]^g+b[n]*x[n]^-g+A*x[n]^3

where g,A are known variables, and i am trying to find a[n],b[n] - the coefficients vectors.

the Boundary conditions are: F(1)=0,F(last)=0,f(n)=f(n+1).

i tried solving it with Solve("This system cannot be solved with the methods available to Solve"),and RSolve(doesn't even attempt to solve it)

any idea how i can solve this?

Thanks
