Differentiation - The Chain Rule

Показать описание
The Chain Rule is one of most important rules in differentiation and allows us to find the derivative of composite functions. This rule alone allows to differentiate an infinite number of different functions and combined with the product rule, allows us to solve almost every differentiation problem!

For a long time I struggled to understand the structural reason why composition of functions turns into multiplication. That is, why is multiplication the natural thing to do? And why is the formula so asymmetric, while it‘s totally nice for addition for example, where it‘s just (f + g)' = f' + g'. My confusion was resolved when I learned that taking the tangent space at a point is a functor from pointed manifolds to vector spaces.

4:03 too many brackets, y=f1(f2…fn(x)…), only 4, 2 sets of 2.

you told where chain rule is used; but u didn't let us see how chain-rule 'works' with graph!

I didnt understand the proof nor how to substitute but i think the vid is very well made maybe i just need to review derivatives plus how to assign functions
