Part 2: Ordinary differential equations. Classical motion under gravity and friction. Laminar regime: Stokes drag. Rayleigh drag. The Malthus and Verhulst growth laws. The 1D harmonic oscillator. The 1D damped harmonic oscillator. The 1D undamped and forced harmonic oscillator. The method of variation of parameters. The method of undetermined coefficients. Beats. Resonant behavior. The 1D damped and forced harmonic oscillator. Constant force. Simple periodic forcing. The case of a general external force: the superposition principle. General periodic forcing: the Fourier series. Fully general forcing: the Fourier transform. The Green’s function.
Part 3: Partial differential equations. Prelude: multivariable calculus. Partial derivatives, gradients, and the Jacobian matrix. The multivariable chain rule. Extrema of multivariable functions: the Hessian and the Taylor expansion for multivariable functions. Curl and divergence. Stationary points of a function of two variables. Second-order Taylor expansion. Coulomb potential. Landau gauge. The 1D d’Alembert equation. The d’Alembert solution (free space and no external forces).
