Key Concepts

Derivative

The derivative is a fundamental concept in calculus that measures the rate at which a quantity changes with respect to another quantity, such as time. It provides the slope of the tangent line at any point on a curve, representing an instantaneous rate of change.

Product Rule

The product rule is a technique used in differentiation to find the derivative of a product of two functions. When two functions are multiplied together, the derivative is given by the derivative of the first function times the second function plus the first function times the derivative of the second function.

Chain Rule

The chain rule is a method for differentiating composite functions. It states that if one function is composed with another, the derivative of the composite function is the derivative of the outer function evaluated at the inner function multiplied by the derivative of the inner function.

Related Rates

Related rates problems involve determining how the rate of change of one variable is connected to the rate of change of another variable. This technique applies differentiation with respect to time to equations that relate multiple variables, enabling the calculation of one unknown rate given others.
