Solving second order ODEs - Motion of a simple pendulum

Objective: The Matlab code is divided into 2 parts. One part is to determine the function values of the reduced first order ODE and the other part is to simulate the motion of a pendulum. function [dtheta_dt] = simple_pendulum(t,theta,b,g,L,m) %Reducing the second order ODE to a first order ODE using the substitution theta=theta1…
