WebbSection 1 The chain rule In the last worksheet, you were shown how to nd the derivative of functions like ef(x) and sing(x). This section gives a method of di erentiating those functions which are what we call composite functions. The method is called the chain rule. The chain rule allows us to di erentiate composite functions. Webb20 mars 2024 · There are two forms of chain rule formula as shown below: Formula 1: d/dx ( f (g (x) ) = f’ (g (x)) · g’ (x) Example: Find the derivative of d/dx (cos 2x) Solution: Let cos 2x = f (g (x)), then f (x) = cos x and g (x) = 2x. Then by the chain rule formula, d/dx (cos 2x) = -sin 2x · 2 = -2 sin 2x Formula 2: dy/dx = dy/du · du/dx

An Example Derivative Using the Product and Chain Rules with

WebbThe chain rule is one of the most powerful tools for computing derivatives. There are two forms of it: ( f ( g ( x))) ′ = f ′ ( g ( x)) ⋅ g ′ ( x). d y d x = d y d u d u d x. The two versions mean the exact same thing, but sometimes it's easier to think in terms of one or the other. The first version is best for computing derivatives of ... WebbNote that it is possible to avoid using the quotient rule if you prefer using the product rule and chain rule. This is because every function that can be written as y = f ( x) g ( x) we can also write as y = f ( x) g ( x) − 1. Hence, the quotient can be written as a product but where g ( x) − 1 is a chain. Again, see Example 3.
