I am having a course on classical mechanics and find it rather hard..I mean its just too mathematical for me.. I find that lagrangian is mostly about changing coordinates and using formulas... but when I come to doing problems myself i find them quite difficult, like simple problem such as prooving FERMAT's law with calculus of variations.. and so on.. It just seems that I do not know how and where to start(adsbygoogle = window.adsbygoogle || []).push({});

What can I do bout this? is there any recomendation from u guys? any book recommandations?

I just feel that a book by thorton is easier understanding and yet encluding more details than the goldstein one.. am i misjudging?
