What is "Differential Calculus" by Ghosh and Maity?

Before we dissect Part 2, it is essential to understand the textbook's standing in Indian mathematics education.

Authors: B.C. Ghosh and S.P. Maity
Publisher: New Central Book Agency (NCBA), Kolkata
Target Audience: B.Sc. (Honours & General) students, mainly in their first and second years of college. differential calculus ghosh maity part 2 pdf

The book is known for:

  • Topic-wise segregation: Each chapter begins with clear theoretical foundations, followed by solved examples, and then an ocean of unsolved practice problems.
  • Exam-oriented approach: Problems are often directly lifted from university question papers (Calcutta University, Burdwan, Vidyasagar, etc.).
  • Rigor: Unlike many Western textbooks that focus on applications, Ghosh & Maity emphasize mathematical proof and technique.

4. Important Legal & Ethical Note

Copyright Status: The book is still under copyright protection (typically life of author + 60/70 years). B.C. Ghosh passed away several decades ago, but K.C. Maity and publishers hold rights. This is an informative content piece tailored for

  • Free PDFs found on websites like Library Genesis, Academia.edu, or student Telegram channels are unauthorized copies.
  • Legal alternatives:
    • Google Books / Amazon Kindle – Check for official ebook edition.
    • Kalyani Publishers’ website – Sometimes offers digital copies.
    • University library – Physical copy or institutional digital access.
    • Used book stores – Low-cost physical copies.

⚠️ Avoid downloading from suspicious pop-up ad sites. They often contain malware, not the actual PDF.

Chapter 12 – Chain Rule & Implicit Functions

  • Multivariable chain rule – matrix‑form (Jacobian) and scalar form; several examples with cylindrical and spherical coordinates.
  • Implicit Function Theorem (IFT) – statement and proof for two variables; applications to determine dy/dx for curves defined implicitly.

Practical use: The IFT section is concise enough to be read in a single lecture, yet it gives students the confidence to handle “y as a function of x” in higher dimensions. What is "Differential Calculus" by Ghosh and Maity

Chapter 14 – Extrema of Two‑Variable Functions

  • Critical points classification – Hessian matrix, determinant test (Δ = fₓₓfᵧᵧ – (fₓᵧ)²).
  • Global extrema on closed bounded regions – use of boundary analysis (parameterisation of the boundary).
  • Constrained extrema revisited – Lagrange multipliers with two constraints (brief).

Illustration: The book solves a classic “maximize volume of a rectangular box with given surface area” problem, showing both the unconstrained and constrained viewpoints.
