Definition of chain rule
WebDec 9, 2015 · Recall the multivariable chain rule. Theorem (Multivariable Chain Rule). Suppose g: R n → R m is differentiable at a ∈ R n and f: R m → R p is differentiable at g ( a) ∈ R m. Then f ∘ g: R n → R p is differentiable at a, and its derivative at this point is given by. D a ( f ∘ g) = D g ( a) ( f) D a ( g). WebMar 25, 2024 · The chain rule helps us differentiate the composition of functions. It is often the case that the variables and can be linked by an intermediate variable . If , where , then , meaning that and are linked through the composite function . Here is an informal argument, using differentials, that If , then by definition To make things a little ...

WebThe chain rule, or general product rule, calculates any component of the joint distribution of a set of random variables using only conditional probabilities. This probability theory is used as a foundation for … WebAug 28, 2007 · The chain rule can be thought of as taking the derivative of the outer function (applied to the inner function) and multiplying it times the derivative of the inner …
WebThe derivative of a function describes the function's instantaneous rate of change at a certain point. Another common interpretation is that the derivative gives us the slope of the line tangent to the function's graph at that point. Learn how we define the derivative using limits. Learn about a bunch of very useful rules (like the power, product, and quotient … WebIt is. h ( t) = f ( g ( t)). The function h ( t) is an example of a composition of functions, meaning it is the result of using function g and then using the function f. We often write h = f ∘ g or h ( t) = ( f ∘ g) ( t). The chain rule is the rule we use if we want to take the derivative of a composition of functions.
