Study Plan

1
Day 1–2

Learn the Theory

Read the textbook chapter carefully. Note down definitions, formulas and key ideas. Focus on: 1. Relations and Their Types, 2. Functions: One-One, Onto, and Bijective, 3. Composition of Functions and Inverse.

2
Day 3

Practise

Solve the textbook exercises and extra practice questions. There are 119 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 Relations and Functions after a week. Use flashcards for quick recall and try past exam questions on this chapter.

What to Focus On

  • A relation in A is a subset of A × A.
  • Empty relation: R = ϕ.
  • Universal relation: R = A × A.
  • Equivalence classes are mutually disjoint.
  • The union of all equivalence classes is the whole set.
  • For 2 divides a-b on Z, [0] is the even integers and [1] is the odd integers.
  • One-one means distinct inputs have distinct outputs.
  • Many-one means different inputs may have the same output.
  • Onto means every codomain element has a preimage.

Common Mistakes to Avoid

A relation from a set to itself must connect every element to every other element.

Empty relation and universal relation mean the same thing.

If a relation is symmetric, then it must also be transitive.

Memory Tips

Empty relation and universal relation

Reflexive, symmetric, transitive

Equivalence relation as partition

Relation on integers given by 2 divides a-b
