Beware of counterfeit copies sold on roadside stalls. To get the genuine 5th or 6th edition:

ISBN Reference (for 6th Edition): 978-9354511123 (verify before purchase).

If there is one reason to buy this book, it is the numerical methods section. Kumbhojkar uses iterative tables and error analysis charts. engineering mathematics 4 by kumbhojkar edition

Author: G. V. Kumbhojkar
Publisher: Jaico Publishing House
Target: Typically for Semester 3 or 4 of engineering (depending on university).

Do not get bogged down by proofs. Kumbhojkar often writes proofs in small font—these are supplementary. Focus on the conditions (e.g., for Cauchy’s theorem: function must be analytic on a simply connected domain). Beware of counterfeit copies sold on roadside stalls

Week 1–2: Fourier series — theory and half-range expansions
Week 3–4: Fourier transforms and applications
Week 5–7: PDE basics — classification, separation of variables, 1D heat & wave equations
Week 8: Laplace transforms and application to PDE/ODE initial-value problems
Week 9–10: Boundary value problems and eigenfunction expansions
Week 11: Special functions (Bessel, Legendre) and orthogonality
Week 12: Vector calculus and integral theorems (brief)
Week 13: Numerical methods for PDEs (finite differences)
Week 14: Revision, advanced problems and exam preparation

At the end of each chapter, problems are categorized as: For students cramming before exams, this is gold

For students cramming before exams, this is gold. You can literally see repeating patterns.

Why it fails: Kumbhojkar’s theoretical explanations are concise, sometimes too concise. The real learning is in the 10+ solved examples that follow each theorem. Fix: Read the theorem once, then immediately do Example 1 and 2. Refer back to theory only if stuck.

The book you're referring to seems to be part of a series or a specific volume focused on engineering mathematics. The author, likely Dr. Tekamrao Kumbhojkar, is known for writing textbooks that are used by engineering students.
