The Numerical Solution by Modified Adomian Decomposition Method for General Wave Equation

Jeriko Abadi Putra, Muhammad Alfa Ridzi, Hafnani, Rahma Zuhra • Jul 2019

SCIENCE AND TECHNOLOGY FOR NATION PROSPERITY, The 2nd International Conference on Science and Technology, Bengkulu, 6 - 7 Juli 2019, Bengkulu, UNIB Press, 77-85, 978-602-5830-19-8.

The Adomian decomposition method and its modification are great methods used to solve a nonlinear equation in calculus of variations. Many researchers work in this method to solve problems in mathematics, physics, biology, and chemistry. In this paper, we apply modified Adomian decomposition method for wave equation problem. Then, we compare the result to exact solution and ordinary Adomian decomposition method. By using software MATLAB, we also plot the numerical solution to this problem.
