Key Topics to Revise

1

Increasing and Decreasing Functions

  • A function is increasing on an interval if its derivative is positive throughout that interval.
  • A function is decreasing on an interval if its derivative is negative throughout that interval.
  • If \( f'(x) > 0 \) for all \( x \) in \( (a, b) \), then \( f(x) \) is increasing on \( [a, b] \).
2

Maxima and Minima

  • Maximum and minimum values occur at critical points where \( f'(x) = 0 \) or where the derivative does not exist.
  • Local maxima occur where the derivative changes from positive to negative.
  • Local minima occur where the derivative changes from negative to positive.
3

Applications of Maxima and Minima

  • Real-world problems like maximizing area, volume, or profit, and minimizing cost or material can be solved using derivatives.
  • The process involves forming a function based on the problem, finding its derivative, and solving for critical points.
  • Always check the nature of the critical point using the second derivative or sign change of the first derivative.
