The Chain rule: What the heck is it? -- Calculus -- ThatTutorGuy.com

In this video, I explain how to use the chain rule.

But for this intro video it's just the basics on the chain rule.

I'm not going to throw you any major calculus theory about where the chain rule comes from. That will just confuse you, and besides, I don't really know where this thing comes from. Instead, in this video I'll show you how to spot whether a problem needs the chain rule or not, because that's the crucial first step in any derivative problem. In later videos we'll get into how to actually use the chain rule in each problem type.
