Vector representation of curves, parameterization, and arc length. Serret-Frenet Formulas: Understanding Tangent ( ), Principal Normal ( ), and Binormal ( ) vectors. Curvature and Torsion: Deeper insights into kappa ( ) and tau (
The strength of the Krishna book lies in its examples. Recreate the derivations for the helicoid, catenoid, and torus independently to build computational stamina.
The physical book costs around ₹350-₹450. For a subject like Differential Geometry (where you need to see equations clearly), the physical copy is superior to a scanned PDF.

You can buy the hard copy from major academic bookstores or online retailers in India. It is generally very affordable compared to international textbooks.
Differential geometry is a core branch of mathematics that uses the tools of calculus and linear algebra to study geometric shapes, curves, and surfaces. For students, researchers, and candidates preparing for competitive exams like UPSC (Mathematics Optional), CSIR NET, GATE, and postgraduate university degrees, is widely considered a foundational textbook.
Differential geometry is a cornerstone of modern mathematics, bridging the gap between calculus, linear algebra, and topology. For students and researchers in Indian universities and competitive exams like CSIR NET, GATE, and civil services, the is a widely sought-after resource. If you are looking for free, open-source PDF
