Hello, when I NDSolve a 2nd order DE, I cant seem to give two boundary conditions at different point of an interval I am solving it on: NDSolve[{f''[x]==K^2*Sin[f[x]],f'[-L]==A, f[-L]==B},f,{x,-L,L}] produces good result, but i.e. NDSolve[{f''[x]==K^2*Sin[f[x]],f'[-L]==A, f[L]==B},f,{x,-L,L}] ____here derivative is given at left edge, but the functi0n itself is given at the right edge___ produces error: NDSolve::"bvlin" "The differential equation(s) and/or boundary conditions are not linear in the dependent variables. NDSolve requires linearity to compute the solution of a multipoint boundary value problem. " Is there a way around this? Thanks YZ
