The Chain Rule of Differentiation: Understanding the Derivative of the Composition of Two Functions

f'(g(x))g'(x)

The expression f'(g(x)) * g'(x) represents the derivative of the composition of two functions, f(x) and g(x)

The expression f'(g(x)) * g'(x) represents the derivative of the composition of two functions, f(x) and g(x).

To evaluate this expression, we need to apply the chain rule of differentiation.

The chain rule states that d/dx [f(g(x))] = f'(g(x)) * g'(x), where f'(g(x)) represents the derivative of f(g(x)) with respect to g(x), and g'(x) is the derivative of g(x) with respect to x.

Let’s break down the steps to find the derivative of the composition:

Step 1: Find the derivative of f(g(x)) with respect to g(x).
This is represented by f'(g(x)). Here, we differentiate f(x) with respect to its variable, which is g(x). Let’s call this derivative F'(g).

Step 2: Find the derivative of g(x) with respect to x.
This is represented by g'(x), which is the derivative of g(x) with respect to x.

Step 3: Multiply f'(g(x)) and g'(x) to get the final result.

So, f'(g(x)) * g'(x) = F'(g) * g'(x).

Note: The derivative F'(g) with respect to g(x) is not a single value but a whole function. To evaluate it further, we would need additional information about the function f(x) and the function g(x).

Overall, f'(g(x)) * g'(x) represents the chain rule of differentiation, which allows us to find the derivative of the composition of two functions.
