Five directions, one gradient: Tutorial 6 Q10 from zero
A slow, narrated walk through all five parts of Q10: the quotient rule step by step, the gradient at the point, and every direction as a point on a circle. Press play, keep the sound on, and answer the four questions it stops to ask you.
About nine minutes, watch once (use ⏮ ⏭ to replay a scene). The narration stops four 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.
Redo Q10 on paper without pausing, then check it against the written solution in the tutorial companion. The rules are in the Module 5 notes §2, and the whole Q8–Q12 set is in the W4 walkthrough.
