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
