dq=sdx+tdy⟹t=dq−sdxdyd q equals s space d x plus t space d y ⟹ t equals the fraction with numerator d q minus s space d x and denominator d y end-fraction
Dr. M.D. Raisinghania spent years compiling examples, checking proofs, and structuring the book to maximize student success. That effort deserves compensation. When you buy (or legally access) his book, you are not just buying paper or bits – you are buying into his teaching method.
For generations of mathematics students, engineers, and competitive exam aspirants in India and beyond, the name is synonymous with clarity, depth, and rigorous problem-solving in differential equations. His book, Advanced Differential Equations , is a cornerstone text for postgraduate mathematics (M.Sc.), B.Tech., and preparations for the CSIR-NET, GATE, and IIT-JAM exams.
