Hi,

How can I let

f''[x] //. {f'[x] -> f[x]}

do the obvious and simplify to f[x]? My mathematica (5.0) just leaves f''[x] standing there. Of course I can easily use

f''[x] //. {f'[x] -> f[x],f''[x] -> f'[x]}

but in my real problem there are a lot more higher derivatives on the LHS, and I want to replace them all in one go.

Thanks a lot,

Ciro.
