Das And Mukherjee Differential Calculus Pdf 【360p】

Theorem (Mean Value Theorem). If f is continuous on [a,b] and differentiable on (a,b), then there exists c in (a,b) with f'(c) = (f(b)-f(a))/(b-a).

Published by U.N. Dhur & Sons Pvt. Ltd., Kolkata, the Das and Mukherjee series (including Integral Calculus and Vector Calculus) is known for its rigorous approach to problem-solving. Unlike many Western textbooks that focus heavily on geometric intuition, this book bridges the gap between theoretical proofs and the intensive problem-solving required for competitive exams like the IIT JAM, ISI, CMI, and the West Bengal Joint Entrance Examination (WBJEE).

The text provides rigorous proofs of Taylor’s Theorem (various forms, including Lagrange’s and Cauchy’s remainders) and Maclaurin’s Expansion. It distinguishes itself by including expansions for obscure functions not found in typical US texts (e.g., $\tan^-1x$, $\sec x$). Theorem (Mean Value Theorem)

The book covers areas often glossed over by other texts. Topics such as Infinite Series, Mean Value Theorems (Rolle’s and Lagrange’s), and Curvature are dealt with in great detail. The section on "Maxima and Minima" is particularly noteworthy for its extensive collection of optimization problems. Dhur & Sons Pvt
