Derivative: A derivative measures the rate at which one quantity changes with respect to another. It gives us information about the slope or steepness of a function.
Differentiation: Differentiation is the process of finding derivatives. It allows us to analyze and understand how functions change over time.
Chain Rule: The chain rule is a formula used to find the derivative of composite functions. It helps us differentiate functions within other functions by breaking them down into smaller parts and applying derivatives separately.
