MATH U101 · Narrated walkthrough · Module 1 §11.5
Area between polar curves, from the first move
A short narrated lesson on 2023 mid-sem Q4. Press play, keep the sound on, and answer the three questions it stops to ask you.
How to use this
About five minutes, watch once. The narration stops three times to ask what the next move is. Commit to an answer before it continues: those pauses are the point, because they practise starting a question, not following one. Captions are on by default; the full transcript is below the player.

After watching
Do the same four moves on a fresh question: start drill, family F1 (polar area). The routine this walkthrough acts out is written up in how to start, and the full written solution with its figure is on the past-papers page. For the rules themselves, see Module 1 notes.
