UP Board Class 11 Maths Book – Relations and Functions
The chapter “Relations and Functions” in the UP Board Class 11 Maths Book introduces students to one of the most important concepts in algebra. It begins with the idea of ordered pairs, Cartesian products, and how sets can be linked through relations. Students learn different types of relations, such as reflexive, symmetric, and transitive, which help in understanding logical connections between elements.
The chapter then explains the concept of functions, where every element of one set is uniquely paired with an element of another set. It covers types of functions, domain, co-domain, range, and real-life applications. Graphical representation of functions helps students visualize mathematical relationships more clearly.
With clear definitions, solved examples, and well-graded exercises, this chapter strengthens analytical and reasoning skills. Understanding Relations and Functions is essential for mastering higher-level mathematics, including calculus and coordinate geometry.
