I have that book on college's library. It's actually good, however, you lose a few dignity points whenever you take it.

I used to need a book of the same author about databases, but couldn't bring myself to get it (I blame my tastes in searching "fairy onaho" on many fap sites and getting similar stuff to what you see on this book's cover).

Either way, how that book deals with integrals is simply genius. My high school education was shit (I got good grades, but what it's worth if they didn't taught you what really matters?), and as a result I bombed at college, and if I simply saw the picture where a guy straightens a sigma to make the integral symbol, I'd not fail Calculus at college that hard.

Oh, the girl holding a newspaper is a heavy drinker, if you're into that. (the alcoholic, big eater and straight man right at the cover, for ye tropers).

These books are also relatively cheap, and you can treat them as the kawaii uguu's version of the "For Dummies" books.
