Overview

Application of derivatives connects calculus with change, motion, growth, and optimisation. The main ideas are rate of change, increasing and decreasing functions, local maxima and minima, and absolute extrema on closed intervals. Derivatives help identify where a function rises, falls, turns, and r

Key Concepts

If y varies with x by

If y varies with x by a rule y = f(x), then dy/dx represents the rate of change of y with respect to x. If x = f(t) and y = g(t), then the chain rule

Marginal cost is the instantaneous rate

Marginal cost is the instantaneous rate of change of total cost, MC = dC/dx. Marginal revenue is the rate of change of total revenue, MR = dR/dx. In t

A function is increasing if larger

A function is increasing if larger x gives larger or equal function values, decreasing if larger x gives smaller or equal values, and constant if all

A point c in the domain

A point c in the domain of f at which either f'(c) = 0 or f is not differentiable is called a critical point.

A local maximum is a point

A local maximum is a point where the function value is greatest in a small neighbourhood, and a local minimum is a point where it is smallest in a sma

Learning Objectives

  • Understand how derivatives measure rate of change of a quantity.
  • Use chain rule to relate rates when two variables depend on time.
  • Identify increasing, decreasing, and constant functions from the sign of the derivative.
  • Find local maxima, local minima, and points of inflexion using first and second derivative tests.
  • Find absolute maximum and minimum values on closed intervals.
