"Engineering Mathematics Volume 1" by T.K.V. Iyengar is a popular textbook among engineering students due to its:

: Eigenvalues, Eigenvectors, Cayley-Hamilton theorem, and Echelon form.

Because the syllabus rarely changes, an older edition (e.g., 2014 or 2015) is 95% the same as the 2024 edition. You can buy a used copy on OLX, BookChor, or your college seniors for ₹100-₹150.

: The text is designed to be user-friendly, adding minor steps between complex lines to ensure students can follow along with "minimum effort".
