Derivative: A mathematical concept that represents the rate of change of a function at any given point. It can be thought of as the slope of a tangent line to the graph of the function.
Chain Rule: A rule used to find derivatives when functions are composed together. It allows us to break down complex functions into simpler ones and calculate their derivatives separately.
Implicit Differentiation: A technique used to find derivatives when an equation involves both dependent and independent variables. It treats one variable as implicitly defined in terms of another and differentiates accordingly.
