``Re: Why does this entry exist?'' by archibal on 2004-03-03 09:04:02
Right. So why this entry? If it's just that the proof is easier, it makes more sense to add a special-case proof attached to the other entry.

Perhaps this is intended as a simplified version for people who would be confused by the real result? If so, it should include the converse (especially since it asserts that the derivative and integral operators are inverses but only shows they are one-sided inverses). The converse is easy for nice enough (C^1 will do) functions.
