Chain Rule: The chain rule is a calculus rule used to find the derivative of composite functions. It allows us to calculate how changes in one variable affect another variable through an intermediate function.
Implicit Differentiation: Implicit differentiation is a technique used to find derivatives when an equation cannot be easily solved for one variable. It involves treating one variable as a function of another and differentiating both sides of the equation.
Optimization: Optimization involves finding the maximum or minimum value of a function within a given range. It often requires using calculus techniques such as finding critical points and applying optimization formulas.
