[edit] Fundamental lemma of calculus of variations

I removed your proof at that article, as it is wrong. To be correct, the function h needs to be chosen in a very carefull manner, not any function would do.

The proof is fixable, but I am not sure it is worth the trouble. Wikipedia being an encyclopedia, proofs are not so much encouraged. Cheers, Oleg Alexandrov (talk) 03:53, 29 March 2006 (UTC)
