Learn Relations and Functions in Mathematics
Welcome to the critical foundational chapter of CBSE Class 12 Mathematics: Relations and Functions. Building upon the basic concepts of sets and mappings introduced in Class 11, this chapter takes a deeper dive into the specific mathematical linkages that bind different sets of data together. It serves as the absolute bedrock for understanding advanced calculus, including continuity, differentiability, and integration. In the real world, understanding how specific inputs map to specific outputs is essential for a wide variety of fields ranging from computer science and cryptography to economics and structural engineering. Mastering this chapter means unlocking the core logic that governs advanced mathematical modeling.
In this chapter, you will transition from simple set mappings to understanding the rigorous properties that define complex mathematical relationships. You will explore Types of Relations, focusing heavily on how to prove whether a relation is reflexive, symmetric, and transitive in order to classify it as an Equivalence Relation. Furthermore, the syllabus thoroughly covers Types of Functions, challenging you to prove whether a given function is One-One (Injective), Onto (Surjective), or Bijective. You will also learn to compute Composite Functions (such as f(g(x))) and logically determine the Inverse of a Function, mathematical skills that are crucial for algebraic manipulations.
The infographic above visually deconstructs the essential mapping rules for One-One (Injective) and Onto (Surjective) functions, illustrating how elements in domain X either map uniquely or comprehensively onto co-domain Y. In your CBSE Class 12 board exams, this chapter carries significant weight and is primarily tested through theoretical proofs—such as proving a given relation is an equivalence relation or demonstrating that a function is mathematically invertible. A quick, highly effective tip for scoring maximum marks in this section: always explicitly define the domain and co-domain of the function at the beginning of your answers, and practice writing step-by-step logical deductions for your equivalence proofs rather than just stating the final conclusion.
Grasping the abstract theoretical concepts of relations and functions can sometimes feel overwhelming, but you certainly don't have to tackle it alone. If you find equivalence relation proofs, bijective mapping, or calculating composite functions challenging, connect with highly experienced, verified CBSE Class 12 Mathematics tutors on the UrbanPro platform. Whether you prefer personalized one-on-one online sessions or focused offline tuition near you, UrbanPro offers a trusted directory of expert educators ready to simplify complex theories, provide targeted practice materials, and help you confidently achieve top board exam results.

With 26 years of extensive experience in teaching mathematics, I specialize in instructing students from grades 9 through 12 across various boards, including CBSE, ICSE, and State Boards. My academic qualifications include a BSc, BTech in Mathematics, MSc, BEd, and I am currently pursuing a PhD. This strong educational background, coupled with my long-standing commitment to teaching, has allowed me to develop a comprehensive approach to mathematics education. I have held prestigious positions as a College Associate Professor at esteemed institutions such as Ganga Institute of Technology and Management, VAISH College, and BLS University. My dedication to teaching has been recognized with the Best Teacher Award from both VAISH College and Ganga Institute of Technology and Management. These accolades reflect my commitment to delivering high-quality education and fostering academic excellence in my students. Currently, I run my own offline center where I conduct mathematics classes for students in grades 9 through 12. In addition to my offline classes, I also offer online sessions to provide flexible learning options. My teaching methods involve practical sessions using a whiteboard to facilitate a clear and engaging learning experience. I emphasize the importance of regular assessments, providing my students with notes, assignments, and weekly tests to track their progress and ensure thorough understanding. My approach to teaching mathematics is rooted in practical application and interactive learning. By focusing on real-world problems and fostering a supportive learning environment, I aim to help students build a strong foundation in mathematics, achieve academic success, and develop a lifelong appreciation for the subject.
Excellent! She explains concepts clearly and is always willing to help. Thank you for always being approachable and supportive.
I have taught maths with more than 24 years experience,I tech maths in my own Coaching Institute .I prepare class 12 students for JEE main so that they can clear JEE exam without dropping a year. My last year 12th student Ashu scored 97.5 percentile in maths in JEE-2024. My student Kartik has scored 100 out of 100 in CBSE class 12th examination.
Vinod Sir's experience is visible in his teaching. I asked him to study the most difficult topic of mathematics Integration which he explained very easily, I did not even need to ask any doubt. While taking class from Sir it felt as if Sir was standing in front of me and teaching me offline. Sir has more than 25 years of experience in teaching maths which is visible in Sir's teaching.
My teaching exp.11 year in most reputed coaching in india. Mentor of jee top rank air-12 yatis agrawal, 19, 28 many more in top 100 in jee adavnced. Many of students got 100%tile in jee mains along with 100% marks in board exams. I also provide complete relevent study material like worksheet, practice sheet , dpps , assignment etc. Daily quizz based on assignment. Periodically test papers topic wise, minor and major as per shedule. I have helped thousands of students overcome their fear of maths.
