Asymptotic methods and pertubation method

[hanson]

Hi all!
I am currently reading a book on asymptotic and pertubation methods for finding approximate solutions.

How asymptotic methods and pertubaion methods are related? I mean, can I skip asymptotic methods and directly jump to study pertubation methods? (I know it may be better to have a thorough view on the subject. But I am really out of time.)

Please kindly help.

Is it Bender&Orszag you're reading?

The perturbation chapter is relatively understandable without the other stuff, I think (although I recommend you reading it!)

exactly. But, I am a but crap in math actually.
I face quite a lot problems rading that book.
You've read that book, right? could you please help answer some of my questions?
