Interactive video lesson plan for: When do you use chain rule? (KristaKingMath)

Activity overview:

People ask this question all the time. When do I have to use chain rule, and when can I get away with not worrying about it? Usually, they're trying to look for a set of rules they can follow that will tell them when they can ignore chain rule altogether, because it's a hard thing that they want to avoid if they can.

The problem is that, while there are rare instances where applying chain rule won't effect the derivative or the integral, it's much easier to consider chain rule every single time you take the derivative or the integral, rather than trying to figure out when you can ignore it.

The bottom line is that chain rule has to be applied to every single derivative, and every single integral. Sometimes it won't effect the result, but that's only because applying it means you're multiplying by positive one or dividing by positive one. But you're still applying chain rule.

In this video, we're going to look at why chain rule should always be applied, and show the particular kind of function where applying it won't effect the derivative or the integral.

Hi, I’m Krista! I make math courses to keep you from banging your head against the wall. ;)

Math class was always so frustrating for me. I’d go to a class, spend hours on homework, and three days later have an “Ah-ha!” moment about how the problems worked that could have slashed my homework time in half. I’d think, “WHY didn’t my teacher just tell me this in the first place?!”

So I started tutoring to keep other people out of the same aggravating, time-sucking cycle. Since then, I’ve recorded tons of videos and written out cheat-sheet style notes and formula sheets to help every math student—from basic middle school classes to advanced college calculus—figure out what’s going on, understand the important concepts, and pass their classes, once and for all.
