Mr. IntegralDifferential Equations: Engineering Checkpoint — Cheat sheet
On this page
Core rule
Model → classify → solve → verify data and residual → inspect stability and units.
Watch for
The expanded course supplies a foundation, not every special-function or partial-differential-equation method. Use the checkpoint to identify gaps: a wrong initial slope suggests missing homogeneous terms; an unexpected jump suggests a forcing error; alternating growth in a decaying model suggests numerical instability.
