solving second order differential equations using matlab

Objective: %solving 2nd order ode\'s using matlab clear all close all clc %inputs b=0.05; g=9.81; l=1; m=1; % initial conditions theta_0 = [0;3]; %time points t_span = linspace(0,20,500); %solve ode [t,results] = ode45(@(t,theta) ode_func(t, theta, b,g,l,m),t_span, theta_0); plot(t,results (:,1)) hold on plot(t,results(:,2)) ylabel(\'plot\')…
