As such, they make handy supplements to college textbooks and serve as valuable pre-exam reviews. Covered in this updated edition are polynomials, radicals, equations and inequalities, polynomial equations, exponential and logarithmic functions, conics, sequences and series, induction, permutations and combinations, determinants and matrices, and more.
