In calculus, the chain rule is a formula that expresses the derivative of the composition of two differentiable functions f and g in terms of the derivatives ...

The chain rule tells us how to find the derivative of a composite function. The AP Calculus course doesn't require knowing the proof of this rule.

Derivation of the Chain Rule. Suppose y = f ◦ g(x). Assuming f and g have derivatives where appropriate, the Chain Rule says that. (f ◦ g)0 = (f0 ◦ g) · g0.

8 мар. 2015 г. · If g is differentiable at a, and f is differentiable at g(a), then f∘g is differentiable at a, and (f∘g)′(a)=f′(g(a))⋅g′(a). Why is the "correct" proof of the chain rule correct? What is ... What is the purpose or proof behind chain rule? How can the chain rule be explained more rigorously? Другие результаты с сайта math.stackexchange.com

The chain rule is used to find the derivatives of composite functions like (x2 + 1)3, (sin 2x), (ln 5x), e2x, and so on. If y = f(g(x)), then y' = f'(g(x)). g'( ...

16 нояб. 2022 г. · Chain Rule If f(x) and g(x) are both differentiable functions and we define F(x)=(f∘g)(x) F ( x ) = ( f ∘ g ) ( x ) then the derivative of F( ...

(f ◦ g)/(a) = f/. ( g(a). ) g/(a). We start with a proof which is not entirely correct, but contains in it the heart of the argument. “Proof.” By ...

27 июн. 2019 г. · In this video we work through a proof of the chain rule. It's not a rigorous proof but it gets the point across and is definitely good ...

A brief look into why the "traditional proof" for Chain Rule is wrong — and how to rectify it to make it complete.
