Cliffs: - ChE & Math double major, currently a junior. - Just got offered a project in ChE department that starts after Thanksgiving. - Project could turn into head start on Thesis, letting me get a masters only a year after my B.S. - Told to learn Sturm-Liouville => Separation of Variables as they apply to PDE's before starting (and I assume their application to transport phenomena, I really wasn't told much as of now). - Am taking a math class on PDE's next semester, which touches on what I should know but not enough and not soon enough. How should I start? What is the best way to learn something without having homework, lectures, quizzes, etc? Is there a good book that anyone can recommend to me for this particular situation? I have my Diff Eq book, which I plan on reading through some and doing some problems out of.
