## Chain Rule for Derivative — Venturing Into The Dark Side Beneath Applied Calculus…

To the surprise of many math enthusiasts and the like, it seems that we have been pulling out on an incredible amount of **calculus modules** these days. Of course, if you have had any terrible experience in learning *just* the mechanics of calculus, this seemingly-relentless outpouring of materials could make you want to puke. However, if that header image appeals to you *at first sight*, it could very well be that your brain was, subconsciously or otherwise, operating alone the line of:

###### Ah! That lovely **Chain Rule** from the calculus textbooks/classes back in the good old days!

You?Except that this time, we have decided to venture into an aspect of it most calculus users probably have never seen before ((or never bother to see?). That is, the somewhat-obscure side about how it is derived *in theory* — and the intuition behind it. Granted, if you’re coming from a background of applied mathematics, all this might sound a bit gibberish/nerve-wracking — let alone will it be very useful to you. However, if you’re on your way of joining the rank of mathematicians, but the proofs of Chain Rule never seem to click, then here is your chance! 🙂 More
