Re: Do you love limits?

We are doing it because I cannot access M right now and do it on my own.


The limit operator is just an excuse for doing something you know you can't.

Re: Do you love limits?

Okay, so what are we doing? The integral, the sum or what limit?


In mathematics, you don't understand things. You just get used to them.
I have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.

Re: Do you love limits?

That is okay, the first one looks like Rolle's or Mean Value might do it, I will post if I get something.

Hi Yusuke00

If f(a)>g(a), then h(x)=f(x)-g(x), otherwise, h(x)=g(x)-f(x). We can see that it is true that h(a)<0 and h(b)>0. Then, we can apply the theorem given here.
