Lecture
This lecture covers the resolution of linear ordinary differential equations of the second order with constant coefficients, including finding the general solution of the homogeneous equation, a particular solution of the inhomogeneous equation, and combining them with initial conditions. Examples include damped harmonic oscillators and forced harmonic oscillators. Different methods are presented for finding particular solutions depending on the form of the source term, such as polynomials, exponentials, and trigonometric functions.
