I don't know if it's correct because I can't understand it. Because I don't know what p0, p1, q0 and q1 are when you introduce them in the proof. And I'm not sure anyone else will either. Can't you state it without them? You are right, you are not good at stating proofs. I do think you understand it, but I don't think the written proof conveys your clarity of understanding. :).

"A={x:a<=x<=p; f(x)>0 on [x,p]}". What is that set? It looks to me like the set of included x's depends on p. As such it should be written A(p). Furthermore if a=x then f(x)=0, so there isn't any p that works anyway. Look at my outline in post #24 and try to follow it.

I think that pretty much says what you want.

I think you should start a new thread with new questions. People will often just pass over an old thread with lots of replies, and I can't answer ALL your questions. Let's give some other people a chance.
