Understanding the Chain Rule in Calculus

The chain rule is a fundamental concept in calculus, especially when finding derivatives of composite functions. It allows us to differentiate complex functions by breaking them down into simpler parts. In simple terms, the chain rule states that the derivative of a composite function is the derivative of the outer function, evaluated at the inner function, multiplied by the derivative of the inner function. This process is essential for solving derivative problems involving nested functions, and forms a crucial part of the foundation for higher-level calculus.
