Partial Differential Equations

Master the partial differential equations the CELE samples, name the order and linearity, recognize the heat, wave, and Laplace equations, classify them as parabolic, hyperbolic, or elliptic with the B^2 - 4AC test, and solve by separation of variables into product solutions pinned down by boundary and initial conditions, with every worked example carried to a clean number with units.
