Rapidsol Partial Differential Equations (Pbi. U)


The present book provides a comprehensive treatment of the concepts and topics by giving a vast variety of examples fully solved. The entire subject matter has been arranged in a systematic, graded, simple, lucid and exhaustive manner. Each chapter begins with some definitions followed by theorems with complete proofs and solved problems. A large number of notes and remarks have been added for a better understanding of the subject.


Partial Differential Equations : Partial differential equation of first order, Lagrange’s solution, Integral surfaces passing through a given curve, surfaces orthogonal to a given system of surfaces, Partial differential equation of first order but of any degree, Charpit’s general method of solution.

Partial Differential Equations of Second and Higher Order : Partial differential equations of the second order and their classification into hyperbolic, elliptic and parabolic types, canonical forms.Homogeneous and non-homogeneous partial differential equations with constant coefficients. One dimension Wave and Heat Equation. Two dimensional Laplace equation by separation of variable and D’Alembert’s solution of wave equation.
