Download NCERT Class 10 Maths Hindi Chapter 2 PDF – संबंध एवं फलन Explained

Mathematics in Class 10 becomes more meaningful when students understand how numbers and quantities connect with each other. Chapter 2 – संबंध एवं फलन (Relations and Functions) is one such important chapter that introduces how one value depends on another. Students can easily download the NCERT Class 10 Maths Hindi Chapter 2 PDF from here to study the concepts in a simple, step-by-step way.

I chose to write about this topic because many students studying in Hindi medium often face difficulty in understanding mathematical terms in their own language. This chapter forms the base for future topics such as coordinate geometry, trigonometry, and calculus. By learning relations and functions now, students can build a clear understanding of how one variable affects another. It also helps in developing analytical thinking, which is useful in board exams as well as in higher studies. That’s why having access to the NCERT PDF and a proper explanation in Hindi is very important.

About NCERT Class 10 Maths Chapter 2 – संबंध एवं फलन

This chapter mainly explains how two quantities are related. For example, if we say x → y, it means the value of ‘y’ changes whenever ‘x’ changes. This connection between two sets is called a relation (संबंध). When every x value has only one unique y value, it becomes a function (फलन). These concepts help students understand patterns in data and use them in problem-solving.

Main Topics Covered in the Chapter

Definition of Relation (संबंध की परिभाषा) – Explains how pairs of numbers or objects are related.
Representation of Relations – Shows different ways to represent relations using arrow diagrams, tables, and ordered pairs.
Definition of Function (फलन की परिभाषा) – Explains that a function gives one output for each input.
Domain, Co-domain, and Range – Basic terms that describe input and output sets.
Types of Functions – Includes one-one, many-one, onto, and into functions.
Practical Examples – Covers examples from daily life and basic mathematical problems.

Why This Chapter Is Important

Understanding relations and functions helps students analyse how quantities are connected in mathematics, science, and even real-life situations. It is the foundation for later chapters and plays an important role in board exams. Usually, questions from this topic carry 4–6 marks and test logical understanding. For example, students might be asked to find whether a given relation is a function or not. Such questions can be easily solved if one has practised the concepts from NCERT.

NCERT Class 11 History Chapter 6 PDF (Hindi): मूल निवासियों का विस्थापन

Chapter 6 of Class 11 History (Hindi Medium), मूल निवासियों का विस्थापन, explores how indigenous communities across Australia, America, and New Zealand were displaced by European settlers. It explains how native populations lived in harmony with nature, practiced unique cultures, and followed their own systems of social organisation long before Europeans arrived. The chapter also describes how colonisation disrupted their lives through land seizure, forced labour, disease, and cultural destruction. It gives a clear picture of how modern nations were built on lands that originally belonged to indigenous people.

While history generally highlights kings, explorers, and governments, this chapter brings us closer to ordinary tribal communities who faced displacement despite being the original inhabitants of their land. Understanding their struggles helps students recognise how colonisation shaped the modern world, and why issues related to indigenous rights, land protection, and cultural preservation are still important today. This chapter encourages empathy and helps readers look at global history from multiple viewpoints, not just from the dominant narratives.

About Chapter 6: मूल निवासियों का विस्थापन

This chapter focuses on the lives of indigenous people before European arrival, the changes brought by colonisation, and the long-term impact on native societies.
