Comparison of Lagrange multipliers for telegraph equations
Abstract
In this paper, we likewise calculate exact langrage multiplier and it progressively connects to the definite results of telegraph equations. This study witnesses the advantages of Exact Lagrange multipliers and their coupling with Variational Iteration Method. Computational work reflects that use of exact Lagrange multipliers reduces the computational work to a tangible level and also increase the level of accuracy. Moreover, exact Lagrange multiplier reduce the successive application of integral operator and are more user friendly.
