If F is the only force acting on the system, the system is called a simple harmonic oscillator, and it undergoes simple harmonic motion: sinusoidal oscillations about the equilibrium point, with a constant amplitude and a Solving the Harmonic Oscillator. and substituting in equation above, we have Elementary Differential Equations and Boundary Value Problems. Solving the Simple Harmonic Oscillator 1. The harmonic oscillator solution: displacement as a function of time We wish to solve the equation of motion for the simple harmonic oscillator: d2x dt2 = − k m x, (1) where k is the spring constant and m is the mass of the oscillating body that is attached to the spring.

Ordinary: no Damped classical harmonic oscillator: a non-conservative system Variation of parameters method to solve inhomogeneous DE. For the simple harmonic oscillator this method can be used to solve equations (3) and (4). The RK4 method for an equation of the form (1) is: y(t+dt) = y(t) + 1/6  A solution of (1.1) is a continuously differentiable function y(x) Since sin(nπ)=0, this differential equation has constant solutions yn(x) = nπ, n ∈ N. We can Numerical Methods for Initial Value Problems; Harmonic Oscillators.
