Relations and Functions — Syllabus & Topics
Topics covered in Relations and Functions for JEE Mains Mathematics.
Topics in Relations and Functions
Relations: Types and Properties
- A relation R from set A to set B is a subset of A × B
- Reflexive: Every element is related to itself (aRa for all a ∈ A)
- Symmetric: If aRb then bRa for all a,b ∈ A
Functions: One-One, Many-One, Onto
- Function f: A → B assigns unique image to each element in domain
- One-one (Injective): Different inputs give different outputs
- Many-one: At least two inputs give same output
Modulus Functions and Inequalities
- |x| = x if x ≥ 0, |x| = -x if x < 0
- |x - a| represents distance from point a on number line
- Properties: |xy| = |x||y|, |x/y| = |x|/|y|, ||x| - |y|| ≤ |x ± y| ≤ |x| + |y|
Trigonometric and Inverse Trigonometric Functions
- sin⁻¹x: domain [-1,1], range [-π/2, π/2]
- cos⁻¹x: domain [-1,1], range [0, π]
- tan⁻¹x: domain R, range (-π/2, π/2)
