3.6: The Chain Rule - Mathematics LibreTexts
Key Concepts The chain rule allows us to differentiate compositions of two or more functions. It states that for \(h(x)=f(g(x)),\) \(h′(x)=f′(g(x))g′(x).\) We can use the chain rule... 展开
When we have a function that is a composition of two or more functions, we could use all of the techniques we have already learned to differentiate it. However, using all … 展开
We can now apply the chain rule to composite functions, but note that we often need to use it with other rules. For example, to find derivatives of functions of the form … 展开
Chain rule - Wikipedia
The full generalization of the chain rule to multi-variable functions (such as ) is rather technical. However, it is simpler to write in the case of functions of the form where , and for each
As this case occurs often in the study of functions of a single variable, it is worth describing it separately.
Let , and for each To write the chain rule for the composition of functions one needs the partial derivativesWikipedia · CC-BY-SA 许可下的文字Derivative Rules - Math is Fun
The Chain Rule says: the derivative of f(g(x)) = f’(g(x))g’(x) (5x−2) 3 is made up of g 3 and 5x−2: f(g) = g 3; g(x) = 5x−2; The individual derivatives are: f'(g) = 3g 2 (by the Power Rule) g'(x) = 5; …

2017年11月12日 · My problem is computing $\frac{\partial H}{\partial W_1}$. I take out $X^T$ from this, by using chain rule, but then it doesn't match the dimesnion for multiplication. How …
The Multivariable Chain Rule Nikhil Srivastava February 11, 2015 The chain rule is a simple consequence of the fact that di erentiation produces the linear approximation to a function at a …
chain rule is called the pain rule . 2 Find the derivative of f(x) = sin(ˇcos(x)) at x= 0. Solution: applying the chain rule gives cos(ˇcos(x)) ( ˇsin(x)). 3 For linear functions f(x) = ax+ b;g(x) = …
