Relations and Functions can be difficult when you have to remember the rules for ordered pairs, Cartesian products, domains, ranges and different types of functions. You may understand the definitions but still struggle to apply them while solving questions.
If you face this problem, PW videos can help you revise the concepts through explanations, examples, practice questions and chapter summaries. These three videos cover the fundamentals of relations, Applied Mathematics revision and advanced concepts for Class 12, helping you choose the lesson that matches your preparation needs.
This Class 11 Maths one-shot covers ordered pairs, Cartesian products, relations, domains, ranges and functions. You will also learn about standard real-valued functions, including rational, root and reciprocal functions, along with questions on their domains and ranges.
The video covers modulus, signum and greatest integer functions, as well as the algebra of real-valued functions. Examples and shortcuts help you connect the definitions with question-solving methods.
Watch this video when you need to revise the complete chapter before a test or exam and practise selecting the correct steps for different types of questions.
This Class 11 Applied Mathematics one-shot focuses on relations and their representation. It covers ordered pairs, Cartesian products involving two and three sets, and methods to express and count relations.
You will learn how arrow diagrams represent relations and how domain, range and co-domain are used in questions. The lesson also explains universal, identity, empty and inverse relations, followed by a summary and homework.
If you are preparing for Applied Mathematics, use this video to revise relation types, understand their representation and practise questions after learning the basic definitions.
This Class 12 Maths revision video covers relations and functions through concepts, MCQs and proofs. You will revise ordered pairs, Cartesian products, relation counting, and empty, universal, trivial and identity relations.
It also explains reflexive, symmetric, transitive and equivalence relations, with proofs based on divisibility and family relations. The functions section covers domain, codomain, range, the vertical line test and different function types, including injective, surjective and bijective functions.
Linear, quadratic, piecewise and higher-power examples help you practise classification and apply definitions while solving questions.
These three PW videos cover Relations and Functions at different levels. Start with the Class 11 Maths one-shot if you need to revise the complete chapter, or choose the Applied Mathematics lesson to focus on relation types and their representation.
If you are revising Class 12 concepts, the third video covers advanced relation types, function classification, MCQs and proofs. Choose the lesson that matches your current needs, make notes of the definitions and methods, and practise questions after watching to check your understanding.
