Definition: The derivative of the product of two functions f(x) and g(x). It represents the rate at which the product of f(x) and g(x) is changing with respect to x.
Analogy: Think of (f(x) * g(x))' as a recipe for baking a cake. Just like you need to know the individual recipes for each ingredient (f'(x) and g'(x)), you also need to know how they come together in the final product.
- f'(x): The derivative of function f(x). It represents the rate at which f(x) is changing with respect to x.
- g'(x): The derivative of function g(x). It represents the rate at which g(x) is changing with respect to x.
- Chain Rule: A rule used to find derivatives when functions are composed or nested within each other.
