Class 12 Mathematics Notes
These are the best notes for Class 12 Mathematics, covering key concepts, formulas, important
theorems, and step-by-step solutions to practice problems.
Each chapter is structured to help you understand the topic effectively.
Chapter 1: Relations and Functions
Overview:
A function is a relation where each element of the domain is related to exactly one element of the
co-domain. Functions are categorized into one-to-one, onto, and many-to-one.
Key Concepts:
- Domain, Range, Co-domain
- Types of functions: Injective, Surjective, Bijective
- Composition of functions
- Inverse of a function
Important Formulas and Theorems
Formulas:
- Domain, Range, and Co-domain of a function
- f(x) = g(x) implies x in Domain of f and g
- Composition: f(g(x)) = f(g(x))
