## Description

2:B & W 6 x 9 in or 229 x 152 mm Perfect Bound on Creme w/Gloss Lam

Review: Classic text - From one of the greatest mathematician of last 100 years , this book is worth every penny.
Review: Briliant exposition - This is a masterpiece written by two pretty influential mathematicians of the nineteenth century. It's an amalgam of two separate volumes, which contain every aspect of undergraduate-level analysis. Some proofs in Riemann integrals have been dealt with the utmost finesse that I've never seen before. The transition from Riemann to Lebesgue integrals has been laid out exceptionally well. The theory and intuition behind every topic are very well explained and clear.
