and its all totally Chinese to me
is there a good website that teaches that stuff with examples?

Before anyone can help you with this I think one clarification needs to be made. You are correct, over the last three weeks are so you have posted quite a few questions here. You almost always eventually recieved a good response to your questions, but you don't seem to understand any of them. Is it possible that some people here (me included) have assumed that you are in Real Analysis when you are in fact in something else? Exactly what class are you in? Are rigorous proofs needed? Other information about exactly what you are seeking would be appreciated so we can better help you.

i am taking a calculus1 course from hell
it on the highest level available in my university
its involves infimalistic math.
i really tried to understand those prooves
but i failed

any good material/video lectures available on this proof stuff

i am really good with solving integrals,limits derivatives

the problem is those prove question

so what should i do?

Unfortunately if you are in a class that covers analysis you cannot avoid proofs. Now I cannot reccomend any website other than this one, but I can reccomend a book that is very thorough and seems to cover about the level of analysis you are studying. It is An Introduction To Analysis (Wade-Prentice Hall). It covers all the material I have seen you post about, also it covers with the same "flavor" that your class seems to have. What I mean is that it is very sequence oriented.To illustrate what I mean recall your question here http://www.mathhelpforum.com/math-he...-question.html . Solutions similar to Laurent's dealing with sequences are prevalent throughout the book. This may be what you are looking for, or it may not. Just be sure to seriously understand the sequence chapter in this book if you end up using it.

Here is a link to the book

Amazon.com: Introduction to Analysis (3rd Edition): William R. Wade: Books

You can decide if it would be helpful for you to use it as a reference


Also, I suppose you could try this site MathLinks :: Index - MathLinks, but I warn you. Half of the people there are actualy professors or doctoral students, so don't expect any simpler proofs.

I hope this helps.

Why choosing Chinese as a language you don't understand ?

Haha...I am not sure if you are kidding. It is an expression meaning he doesnt understand any of it

I know, it's the same in French ^^
But for us Chinese, it sometimes makes no sense

i couldnt find this book you were talking about on the internet.
i cant bye it on the net.
is there any alternative?

i didnt mean to offend the Chinese languege
i ment saying that as an expression

I gave you a link to the book. Other books I could suggest are, Introduction to Analysis (Rosenlicht) and A First Course in Real Analysis (Protter and Morrey)
