2
Day 3

Practise

Solve the textbook exercises and extra practice questions. There are 60 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.

Spaced Revision

Come back to Limits after a week. Use flashcards for quick recall and try past exam questions on this chapter.

What to Focus On

  • A limit describes what a function approaches, not necessarily what it equals at the point.
  • A two-sided limit depends on both left-hand and right-hand behaviour.
  • The notation lim_{x→c} f(x) is the standard limit notation.
  • Direct substitution works only when the function is defined at the point.
  • Theorem 14.2 is a major standard limit for powers.
  • Polynomial products can often be handled immediately by substitution.
  • Factorisation is used mainly when direct substitution gives 0/0.
  • A common factor of the form (x-c) can often be cancelled.
  • Cancellation is valid because the limiting variable approaches but does not equal the point.

Common Mistakes to Avoid

A limit can always be found by direct substitution.

If a function is not defined at a point, its limit at that point cannot exist.

Cancelling common factors is always illegal because the cancelled factor becomes 0 at the limit point.
