The Chain Rule

MIT grad shows HOW to use the chain rule to find the derivative and WHEN to use it. To skip ahead: 1) For how to use the CHAIN RULE or "OUTSIDE-INSIDE rule", skip to time 0:17. 1b) For how to know WHEN YOU NEED the chain rule, skip to time 4:35. 2) For another example with the POWER RULE in the chain rule, skip to time 7:05. 3) For a TRIG derivative chain rule example, skip to time 9:33. 3b) For the formal chain rule FORMULA, skip to time 11:36. PS) For a DOUBLE CHAIN RULE (or "repeated use of the chain rule") example, skip to time 13:33.
