Can anyone explain CHAIN RULE in Derivatives

The title says it all. I didn't understand the chain rule. Can somebody help me?

Exactly what is it that you don't understand?

The chain rule is applied to find the derivative of compositions of functions.

What is dy/dx??? Normally we use d/dx right?

Re: Can anyone explain CHAIN RULE in Derivatives

Sometimes it helps to say to yourself "the derivative of y with respect to x" when using this Leibniz notation, and this will help you as you get more into substitution and so on. If you google "Leibniz notation," a video comes up explaining it perfectly in regards to the chain rule.

No, we don't. "d/dx" without anything else makes no sense. "d/dx f(x)" may be used when "f(x)" is some expression too complicated to be easily written in a fraction but otherwise that would more commonly be written df/dx.
