SHORT ANSWER

Treat explanations as support for your own derivation. Make assumptions and units visible, solve before comparing, and check against the taught method.

The key idea

A generated step can hide an assumption. Ask why a method applies and test whether the dimensions and boundary conditions make sense.

A practical example

Turn one worked problem into a new variant with changed inputs; solve it by hand and inspect each step against lecture notes.

Keep the result checkable

Do not copy a derivation simply because it looks polished. Verify symbols, units, assumptions, and course conventions.
