This is a wonderfully written reference for any math class.  Abstract topics are explained in a manner in which Engineers easily pick them up.  I went through my entire BS pretending to understand math and since we started using this book for my entry level graduate class, I ACTUALLY feel like I understand some of this stuff.<br><br>If your instructor recommends this book, props to him, and lucky you!<br>If you just like math and wound up here without being forced to buy this book, I would get it anyway because its so good.
