The Post: Understanding Linear Differential Operators: A Guide Using the Wave Operator.
Excerpts: here are the three most important ideas from this guide. Operators are Recipes: A linear differential operator is a recipe for combining the derivatives of a function. Coefficients are Measurements: Coefficients determine the amount of each derivative used in the recipe. Multi-Indices are Labels: A multi-index is just a convenient label to specify which derivative a coefficient belongs to.
Programmatic demo: Plot the region where the Principal Symbol is zero for both the Wave Operator-Hyperbolic and the Diffusion Operator-Parabolic.
Relevant File: how to express the wave operator as a general linear differential operator of order two.
