Re: Why in this 1=0?

hi 21122012,

Do you understand the difference between definite integration and indefinite integration ?

First look at

http://en.wikipedia.org/wiki/Fundamenta … f_calculus

When you understand this, the website for integration by parts is

http://en.wikipedia.org/wiki/Integration_by_parts

Hope that helps,

Bob

Re: Why in this 1=0?

Hi Bob,

if I may, it seems to me that the (logical) error is deeper:
because

is just a symbol to denote the class of antiderivatives; so, saying class=number makes me think 21122012 is totally missing the meaning of it all.

Here a problem here in what:

Calculus doesn't distinguish an arithmetic increment from a geometrical increment! ! !

Calculus - bad science! ! !

hi Bob!

I understand integration best of all in the world and I already once proved you it!

It's a joke...

hi Bob!

You haven't prived anything to anyone.

I think I will restrain from replying to threads of yours like this one from now on, as I suggest to everyone else. Nice talking to you, I guess...

??????

I think you looked at the wrong pages.

Good.  So please explain to me the difference between definite integration and indefinite integration.

Thank you for being my teacher.

I'm sorry, but I really don't find the connection you see beetwen this and the main topic...
However, don't you feel a little ashamed by saying "Calculus - bad science! ! !"??
I may be wrong, because i read your first post and didn't either understand what you're talking about... but, honestly, seems to me (and not only to me, as I see) you don't know what an indefinite integral is.

Re: Why in this 1=0?

That that is understood as uncertain integral in Calculus is a nonsense! Because integration is process the return to differentiation. And differentiation is made not with function and with its increment - with its range of definition which contracts to two next elements because

Therefore result of a certain integral - part of range of definition - a function increment, and result of integral with uncertain borders of integration - all range of definition of function. And no families of functions can be! Now I to you will prepare link.

Re: Why in this 1=0?

Give to me the website where this miracle except as here is still written?

This incorrect equality!

I gave you 6 websites.

Did you look at them?

I understand integration best of all in the world

Good.  So please explain to me the difference between definite integration and indefinite integration.

Thank you for being my teacher.

You have not done this.

Why do you waste my time again?

I also shall stop replying if you keep behaving like this.

Bob
