Avkal Sameekaran | B.A./B.Sc. Second Year Semester III | NEP 2020 | Useful for CSIR NET, GATE MA & IIT JAM | Hindi Differential Equations Textbook | Dr. H.K. Pathak

Avkal Sameekaran — Ordinary and Partial Differential Equations — is one of the most heavily tested topics in CSIR NET, GATE MA, and IIT JAM. Yet almost no Hindi-medium textbook covers both ODE and PDE at university level in a single, accessible volume.  This 504-page book fills that gap.  Written by Dr. H.K. Pathak, Ex-Professor and Former Head, School of Studies in Mathematics, Pt. Ravishankar Shukla University (PRSU) Raipur, with 3,400+ Google Scholar citations, this book presents complete Differential Equations — from First Order ODEs to Second Order PDEs — entirely in Hindi, with all theorems, proofs, solved examples and previous year papers written clearly for students who learn better in Hindi.  WHAT THIS BOOK COVERS (NEP 2020 Syllabus, 60 Teaching Hours): Unit I — Prathama Koti Avkal Sameekaran (First Order DEs): Separable, Homogeneous, Linear, Exact equations; Integrating factor; Charpit's form; Singular solutions; Orthogonal trajectories Unit II — Rekhiya evam Yugmit Avkal Sameekaran (Linear and Simultaneous ODEs): Constant coefficients; Second order linear ODEs; Variation of parameters; Simultaneous DEs Unit III — Prathama Koti Aavshanik Avkal Sameekaran (First Order PDEs): Lagrange's solution; Charpit's general method Unit IV — Dviteey evam Uccha Koti Aavshanik Avkal Sameekaran (Second and Higher Order PDEs): Classification; Monge's method  CSIR NET, GATE MA & IIT JAM (HINDI MEDIUM): Lagrange's solution, Charpit's method, variation of parameters and PDE classification are tested directly in CSIR NET Mathematical Sciences, GATE MA and IIT JAM. This is the only Hindi-medium university textbook that covers all these topics in depth, making it invaluable for students preparing for these exams in Hindi.  Specially designed for all Chhattisgarh State Universities — PRSU Raipur, Hemchand Yadav University Durg, Guru Ghasidas University Bilaspur. Useful for Hindi-medium B.A./B.Sc. students at universities across India.  Published by Shree Shiksha Sahitya Prakashan, Meerut. Includes: Previous Year Papers (Solved), Solved Examples, MCQs, Objective Questions, HOTS Questions.
