where can i study from?

fahd

hello evbody..
im studying the chapter on oscillations and harmonic oscillations..including phase spaces etc.etc...our curriculum goes by the book"analytical mechanics" by fowles and cassiday.However iv seen that most of the things that we did in class are not given in the book for which we got some handouts..(ven der pol oscillator, predator prey relationships..etc..etc)
i was just wondering if u cud guide me as to whether there is a source (anoter text book or web source) where i can study the entire topic of osciallations that includes all these topics...I tell ya that its really a mess to have 10 sources,,with litle bits of information?!
thanks
