what does /sci/ actually think of this thing? i see it passed

Not a fan of it. Especially for people who haven't done math in a while or had a shit highschool.

Just get a normal Precalc book.
Personally I can't stand the layout of modern textbooks like Stewart's so I prefer

You can skip the section on isometries/congruences and the such, it doesn't really matter much.
