MATH U101 · Narrated walkthrough · Module 5 §14.5
The gradient and directional derivatives, from the hillside up
A narrated lesson that builds the idea from zero, then solves Tutorial 6 Q8–Q12. Press play, keep the sound on, and answer the four questions it stops to ask you.
How to use this
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.

Written solutions to all five questions are in the tutorial companion. The rules are in the Module 5 notes, taught slowly in the Module 5 lesson (with a direction widget). Then try family F7 in the start drill.
