A Matlab coding problem, plz help. Thx!

Consider the second order differential equation x + x = 0, with 2(0) = 1 and 2(0) = 0. AMATH 301 - Winter 2018 Due Thursday, 1 March, 5:00 This equation models the angle x of a pendulum hanging nearly straight down. g is the acceleration due to gravity, L is the length of the pendulum and is a friction coefficient If we let u z, then we can rewrite equation (3) as a system of two first order equations of the form Consider the second order differential equation x + x = 0, with 2(0) = 1 and 2(0) = 0.
