Formula Explainer: Meaning, Origin, Limits and One Worked Example
Understand a formula instead of memorising it. Get what each symbol means, a plain account of where it comes from, when it fails and one worked example with every arithmetic step written out.

Your prompt
Explain this formula to me: {{formula}}. My course and level: {{course_level}}. Numbers for the worked example, or "choose simple ones": {{example_numbers}}.
Use only what you are confident is standard. If the formula name or its symbols are ambiguous, ask me before explaining. Where you are not sure, write "check your textbook" instead of guessing.
Use these headings. 1) What it means in words: define every symbol, with units. 2) Where it comes from: a short plain account of the idea or derivation at my level. If there are several routes, say you are giving one common route. 3) When it works and when it fails: the assumptions, plus one case where it gives a wrong or meaningless result. 4) One worked example: the substitution, then each arithmetic step on its own line, then the answer with units, then a rough estimate as a sanity check. 5) Two practice questions for me, with no answers.
Do not skip arithmetic steps. I will check the derivation against my course notes.3 inputs still blank. Empty inputs stay as placeholders when copied.

Tips & limitations
Check the result: 1. Redo the arithmetic yourself; each line should follow from the one before it. 2. The assumptions listed match those in your textbook or notes. 3. Follow up every "check your textbook" note the assistant gave you. Example output is illustrative; independently verify calculations, dates, quotations and actions relevant to your task.
