MATH U101 · Narrated walkthrough · Modules 4–6 §14.4 Tutorial 6
Rates along a curve: where can a function peak on a path?
A narrated lesson from basics on Tutorial 6, Q6 and Q7: the chain rule along a path, then the helix and the ellipse solved. Press play, keep the sound on, and answer the four questions it stops to ask you.
How to use this
About seven minutes, watch once. 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.
