🧠 Most Interesting Section (to me)

Section 4.3 – Forced oscillations with damping.
The notes walk through the amplitude vs. driving frequency graph, then drop a small table of “beating” and “resonance” conditions. It’s the first place where math feels like real engineering. The phase lag formula (φ = arctan(...)) is derived cleanly — worth bookmarking. The primary source for AMATH 250 (Introduction to

If you want, I can expand any section into a full PDF-style set of lecture notes with definitions, proofs, and more worked problems — tell me which sections to expand. Nonlinear: Contains terms like $y^2$, $\sin(y)$, $y \cdot

Linear Vector DEs: Introduction to systems of first-order vector equations and sketching phase portraits. Study Tips and Resources

Example: (\fracdydx + 2y = e^-x) leads to (\mu(x) = e^2x) and solution (y = e^-x + Ce^-2x).

Non-homogeneous: Method of undetermined coefficients and variation of parameters. Applications: Mechanical and electrical oscillators. 4. Laplace Transforms Basics: Definitions, inverse transforms, and solving IVPs.
