2
Day 3

Practise

Solve the textbook exercises and extra practice questions. There are 52 questions available for this chapter.

3
Day 4

Revise & Test

Revise key points without looking at your notes. Take a practice quiz and mark weak areas for another pass.

Day 7

Spaced Revision

Come back to Applications Of Derivatives - II after a week. Use flashcards for quick recall and try past exam questions on this chapter.

What to Focus On

  • Absolute extrema are defined on the entire interval or domain.
  • Closed interval + continuity guarantees at least one absolute maximum and minimum.
  • Endpoints may be absolute extrema but not local extrema.
  • Local extrema are neighbourhood-based.
  • Stationary points form only the subset where f'(x)=0.
  • Critical points include both f'(x)=0 and f'(x) undefined.
  • Sign change in f' determines the type of extremum.
  • Positive to negative gives local maximum.
  • Negative to positive gives local minimum.

Common Mistakes to Avoid

A point where f'(x) = 0 is always a local maximum or local minimum.

Critical points and stationary points mean the same thing.

End points can be local maxima or local minima if they are the biggest or smallest values on the interval.
