# Calculus of variations

I'm doing my final year in maths and am just away to start my 4th year project. It involves learning a subject on my own then submitting a report and doing a presentation. The topic I have to do is "Calculus of variations".

I've been reading about the topic briefly on a few webpages and it does seem a bit daunting!

Does anybody know any decent books worth reading that provide a good explanation of the subject? Also, would it be helpful if I revised certain areas of calculus before trying to learn the topic?

Thanks

Any good mechanics book would be an excellent place to start.

Actually, mechanics book most often treat the point from a physicla point of view. Not explaining what a variation is, using $\delta$ and using all kinds of theorems and properties of functions without much scrutiny.
