Exam Notes on NCERT Class 12 Maths Chapter on Relations and Functions
The NCERT Class 12 Maths chapter on Relations and Functions covers several key concepts: Relations Definition: A relation R from set A to B is a subset of the cartesian product A × B A×B. It relates elements of two or more non-empty sets. Types of Relations: Empty Relation: In set A, if no element is related to any element in A, i.e., R = ϕ ⊂ A × A R=ϕ⊂A×A. Universal Relation: In set A, if each element is related to every element in A, i.e., R = A × A R=A×A. Reflexive Relation: If ( a , a ) ∈ R (a,a)∈R for every a ∈ A a∈A. Symmetric Relation: If ( a 1 , a 2 ) ∈ R (a 1 ,a 2 )∈R implies ( a 2 , a 1 ) ∈ R (a 2 ,a 1 )∈R for all a 1 , a 2 ∈ A a 1 ,a 2 ∈A. Transitive Relation: If ( a 1 , a 2 ) ∈ R (a 1 ,a 2 )∈R and ( a 2 , a 3 ) ∈ R (a 2 ,a 3 )∈R implies ( a 1 , a 3 ) ∈ R (a 1 ,a 3 )∈R for all a 1 , a 2 , a 3 ∈ A a 1 ,a 2 ,a 3 ∈A. Equivalence Relation: A relation that is reflexive, symmetric, and transitive. Functions Definition: A function f from set A to B is a relation where every element of A has one and only one image in B. Types of Functions: One to One Function (Injective): If distinct elements of set X have distinct images in set Y. Onto Function (Surjective): If every element of Y is the image of some element of X under f. One-One and Onto Function (Bijective): If the function is both one-one and onto. Composition of Functions: If f: A → B and g: B → C, the composition g ∘ f g∘f is defined as ( g ∘ f ) ( x ) = g ( f ( x ) ) (g∘f)(x)=g(f(x)) for all x ∈ A x∈A. Invertible Functions: A function f: X → Y is invertible if there exists a function g: Y → X such that g ∘ f = I X g∘f=I X and f ∘ g = I Y f∘g=I Y . Here, g is the inverse of f, denoted by f − 1 f −1 . For a function to be invertible, it must be bijective. These concepts form the foundation of understanding how different elements within a set or between different sets are related and how functions act as a special kind of relation with specific properties. The understanding of relations and functions is crucial for further studies in mathematics, especially in calculus, algebra, and discrete mathematics.

Exam notes on NCERT Class 12 Chapter Inverse Trigonometric Functions
The NCERT Class 12 Mathematics chapter on Inverse Trigonometric Functions covers several critical concepts essential for understanding the inversion of trigonometric ratios and their applications, not only in board exams but also in competitive exams like JEE. Here's a detailed summary of the chapter: Concepts Covered Introduction to Inverse Trigonometric Functions: This section explains the concept of finding the inverse of trigonometric functions by restricting their domain and range to make them bijective. The inverse of a function f f is denoted as f − 1 f −1 . Domain and Range of Inverse Trigonometric Functions: Each inverse trigonometric function has a specific domain and range: Arcsine (sin^{-1}x): Domain: [ − 1 , 1 ] [−1,1], Range: [ − π 2 , π 2 ] [− 2 π , 2 π ]. Arccosine (cos^{-1}x): Domain: [ − 1 , 1 ] [−1,1], Range: [ 0 , π ] [0,π]. Arctangent (tan^{-1}x): Domain: All real numbers, Range: ( − π 2 , π 2 ) (− 2 π , 2 π ). Arccotangent (cot^{-1}x): Domain: All real numbers, Range: ( 0 , π ) (0,π). Arcsecant (sec^{-1}x): Domain: ( − ∞ , − 1 ] ∪ [ 1 , ∞ ) (−∞,−1]∪[1,∞), Range: [ 0 , π 2 ) ∪ ( π 2 , π ] [0, 2 π )∪( 2 π ,π]. Arccosecant (csc^{-1}x): Domain: ( − ∞ , − 1 ] ∪ [ 1 , ∞ ) (−∞,−1]∪[1,∞), Range: [ − π 2 , 0 ) ∪ ( 0 , π 2 ] [− 2 π ,0)∪(0, 2 π ]. Properties of Inverse Trigonometric Functions: This section covers various properties that are crucial for solving problems involving inverse trigonometric functions. These properties simplify complex expressions and solve equations involving inverse trigonometric functions. Additional Points Inverse trigonometric functions are not the reciprocals of trigonometric functions. For example, sin ⁡ − 1 x sin −1 x is not equal to 1 sin ⁡ x sinx 1 . Principal Value Branch: The value of an inverse trigonometric function lying in the range of the principal value branch is called its principal value. Equations involving inverse trigonometric functions: This section includes solving equations and finding the values of inverse trigonometric functions given certain conditions. Practice and Problem Solving The chapter includes various problems and exercises to help students apply the concepts of inverse trigonometric functions in different contexts. Practicing these problems is crucial for a thorough understanding and application of the concepts. In summary, this chapter provides comprehensive insights into the inverse of trigonometric functions, their domains and ranges, and properties, along with problem-solving techniques essential for mastering this area of mathematics.
