Part 1 of Class 12 Mathematics covers relations and functions, inverse trigonometric functions, matrices, determinants, continuity and differentiability, and applications of derivatives. This volume transitions you from Class 11 foundations into the calculus-heavy portion of the JEE syllabus.

The chapters on continuity, differentiability, and application of derivatives are where JEE problem-solving truly begins — maxima-minima problems, tangent-normal questions, and Rolle's/Lagrange's theorem applications appear regularly. Master the NCERT exercises here before touching any advanced book. The matrix and determinant chapters are relatively straightforward but form the basis for future topics like linear algebra in engineering college.
