I love Taylor expansions too, but It's really got a dreadful derivation. If I really want to get it, I am going to have to delete my facebook account, youtube account, sell my laptop and everything else I have except study tools and lock myself up with a month's supply bread and butter and isolate myself from everyone for a whole month's break if I am going to master this understanding. Doesn't seem realistic for many of us, but,idk, I might try it. Otherwise, mastery will take a verylong time.####[['Taylor expansions', 'Mathematical_Related_Concept', 'POS'], ['derivation', 'Mathematical_Related_Concept', 'NEG']]
