Solution of Partial differential equation by Lagrange's method | Lagrange's method | B.Tech maths

Описание: 📌 YouTube Description

In this lecture, we will learn the Solution of Partial Differential Equation (PDE) by Lagrange's Method in a simple and step-by-step manner.

Lagrange’s method is used to solve first order linear partial differential equations of the form:

Pp + Qq = R

This topic belongs to the chapter Partial Differential Equation (PDE) in Engineering Mathematics and is very important for B.Tech 1st Year semester exams.
