Partial Differential Equation

Complete Solution of Charpit’s method

Solution: Consider the non-linear partial differential equation f(x, y, z, p, q)= 0 —————————-(1) Since z is a function of x and y, it follows that dz = pdx + qdy —————————————–(2) Let us assume p=u (x, y, z, a), where a is arbitrary constant, substitute in (1) solve to ...

Partial differential equation

Definition: An equation involving partial derivatives is called partial differential equation. Shortly it is written as P.D.E. Some notation for derivatives: Formulation of partial differential equation: (i) Elimination of arbitrary constant and (ii) Elimination of arbitrary function. Procedure of elimination of arbitrary constant: Let us consider the relation g(x,y,z,a,b)=0 ———————————-(i) ...
