Product Rule

Chain Rule: The chain rule is used to find derivatives when one function is nested inside another. It allows us to "unwind" layers of functions and find their individual derivatives.

Quotient Rule: The quotient rule is used to find the derivative of a quotient or division between two functions. It helps us determine how changes in one function affect changes in another.

Derivative: A derivative measures how a quantity changes as its input (usually time or position) changes. In calculus, it represents instantaneous rates of change and slopes of curves at specific points.
