key term - Quotient Rule

Definition

The quotient rule is a formula used to find the derivative of a quotient or division between two functions. It states that the derivative of a fraction is equal to (the denominator times the derivative of numerator) minus (the numerator times the derivative of denominator), all divided by (the square root of denominator squared).

Product Rule:

The product rule allows us to find derivatives when two functions are multiplied together. It helps us determine how changes in one function affect changes in another.

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.

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.
