Question

I watched all the Differentiation Part A videos. In Problem Set 1, part 1F, it looks like I have to use implicit differentiation, but that's not covered until Part B. Can someone explain it for me?

Answer 1

Part 1F is titled both chain rule and implicit differentiation. For Problem Set 1, use the chain rule to find the answers, and do not worry about implicit differentiation. After Session 20, when you do Problem Set 2, you will return to Part 1F and solve problems using implicit differentiation. Keep your Problem Set 1 notes so that you can compare the two techniques - they are two ways to approach a problem.

Answer 2

Thank you!
