Guaranteed 2 Marks! 🧠 Multivariable Calculus | IIT JAM Maths Solutions

In this video, we crack a standard, high-yield question (Q17) from the IIT JAM syllabus concerning a piecewise rational function of two variables $f(x,y) = \frac{5x^2y - 4y^3}{x^2 + y^2}$. We break down how to evaluate simultaneous limits at the origin using path limits and polar coordinates, compute partial derivatives ($\frac{\partial f}{\partial x}$ and $\frac{\partial f}{\partial y}$) at specific coordinate vectors, and test whether a partial derivative is continuous at $(0,0)$ to locate the exact FALSE statement.This concept-clearing lecture covers vital Multivariable Calculus definitions, limit paths, directional behaviors, and differentiation frameworks that are necessary to score high marks in the IIT JAM Mathematics 2026 exam. Whether you are actively solving IIT JAM Previous Year Questions or building your pure math core early for your long-term IIT JAM 2027 Preparation, this step-by-step masterclass will refine your analytical skills and speed up your problem-solving process.

DK MathPrep – Vision & Mission:
The vision and mission of DK MathPrep is to help students from Tamil Nadu secure admission to top-tier institutes such as IIT, ISI, CMI, IISER, TIFR, and IISc. We aim to provide the right guidance, quality coaching, and awareness required for students to achieve their academic goals and pursue excellence in mathematics and science.

Founder of DK MathPrep:
Deepak S is an M.Sc. Mathematics student at IIT Madras. While preparing for IIT JAM and ISI entrance examinations, he realized that there was very little quality content available in both Tamil and English for these exams on YouTube. DK MathPrep was created to bridge that gap and ensure that future aspirants have access to the resources, guidance, and mentorship they need to succeed.
