Braver S. Precalculus Made Difficult 2ed 2023

Textbook in PDF format

Notwithstanding its punchy title, Precalculus Made Difficult is a straightforward textbook that guides students from the Plains of Mathematical Nowhere to the base of Mt. Calculus in just 200 pages. The only mathematical prerequisites are arithmetic and a hazily-recalled past encounter with the rudiments of algebra. It is notable for its concision, style, and emphasis on building deep understanding and intuition. Seth Braver is the author of three other books on mathematics: Lobachevski Illuminated (winner of the Mathematical Association of America's Beckenbach Book Prize), as well as Full Frontal Calculus and The Dark Art of Linear Algebra
