Is it just me or are all textbooks boring and filled with tedious equations and unhelpful examples written by egotistical and elitist authors of their field? Well not this one! I found this book indispensable for all of my physics classes! Clear and concise, out of the 3 classes that required this book (a series), I was able to completely teach myself from this book at least for the first class (covering the first third of the book) without help from confusing lectures. I reference it constantly for almost every class and I highly recommend using tabs or sticky notes to bookmark equations frequently used (I even suck at memorizing equations I use daily lol!)<br><br>So if you have a class that requires this book, be thankful because it is a fantastic supplement for lectures and other books. If it's suggested as optional supplementation, get it!! This is one book I will not be selling back any time soon - totally worth the bucks!
