IIT JAM 2023 Mathematics Q51 | Differentiability & Linear Map

In this video, I solve IIT JAM 2023 Mathematics Question 51, a conceptual Multivariable Calculus problem based on differentiability and linear approximation, explained clearly in Tamil 📘✨

This question tests your understanding of:
✔ Definition of differentiability in R3
✔ Linear map associated with a function
✔ Gradient and total derivative ideas
✔ Evaluating linear approximations numerically

Such definition-based questions are very important for IIT JAM, GATE, and MSc Mathematics entrance exams.

🔹 Conceptual explanation from basics
🔹 No heavy calculations
🔹 JAM-style logical reasoning
🔹 Useful for JAM 2024, 2025 & future aspirants
