## How do you use the chain rule example?

According to the chain rule, h′(x)=f′(g(x))g′(x)=f′(4x)⋅4=4e4x. In this example, it was important that we evaluated the derivative of f at 4x. The derivative of h(x)=f(g(x))=e4x is not equal to 4ex. The only correct answer is h′(x)=4e4x.

### What is differentiation with example?

Differentiation is a method of finding the derivative of a function. Differentiation is a process, in Maths, where we find the instantaneous rate of change in function based on one of its variables. The most common example is the rate change of displacement with respect to time, called velocity.

On what instance does the chain rule of differentiation applicable?

We use the chain rule when differentiating a ‘function of a function’, like f(g(x)) in general. We use the product rule when differentiating two functions multiplied together, like f(x)g(x) in general. Take an example, f(x) = sin(3x).

What is chain rule used for?

The chain rule tells us how to find the derivative of a composite function. Brush up on your knowledge of composite functions, and learn how to apply the chain rule correctly. It tells us how to differentiate composite functions.

## Why is the chain rule used?

### How do you differentiate LN?

To differentiate y=h(x) using logarithmic differentiation, take the natural logarithm of both sides of the equation to obtain lny=ln(h(x))….Solution.

lny=lnx√2x+1exsin3x Step 1. Take the natural logarithm of both sides.
1ydydx=1x+12x+1−1−3cosxsinx Step 3. Differentiate both sides.

How do you explain chain rule?

The chain rule states that the derivative of f(g(x)) is f'(g(x))⋅g'(x). In other words, it helps us differentiate *composite functions*. For example, sin(x²) is a composite function because it can be constructed as f(g(x)) for f(x)=sin(x) and g(x)=x².

What is meant by chain rule?

Definition. • In calculus, the chain rule is a formula for computing the. derivative of the composition of two or more functions. That. is, if f is a function and g is a function, then the chain rule.
