Students can refer to these solutions of RD Sharma Class 12, which helps in gaining knowledge. For better guidance, it is best to solve these solutions. Solving the exercises in each chapter will ensure that students score good marks in the board exams.

RD Sharma Solutions for Class 12 Maths Chapter 1- Relations

Chapter 1 of the RD Sharma textbook deals with relations and their properties, types of relations, inverse of a relation, equivalence relation, some useful results on relations, reflexive relation, symmetric relation, and transitive relation.

Relation: It defines the relationship between two sets of different information. If we consider two sets, the relation between them will be established if there is a connection between the elements of two or more non-empty sets.

Types of Relations: The different types of relations are empty, universal, identity, inverse, reflexive, symmetric, transitive, and equivalence relation.

Representation of Types of Relations

Relation Type Condition
Empty Relation R = φ ⊂ A × A
Universal Relation R = A × A
Identity Relation I = {(a, a), a ∈ A}
Inverse Relation R-1 = {(b, a): (a, b) ∈ R}
Reflexive Relation (a, a) ∈ R
Symmetric Relation aRb ⇒ bRa, ∀ a, b ∈ A
Transitive Relation aRb and bRc ⇒ aRc ∀ a, b, c ∈ A

Meanwhile, in this chapter, students get to learn how to relate graphs of a function and its inverse.

Function: A function is a relation between a set of inputs and a set of permissible outputs with the property that each input is related to exactly one output.

Types of Functions: The types of functions are constant, identity, modulus, integer, exponential, logarithmic, reciprocal, and square root functions.

Inverse Function: An inverse function or an anti-function is a function that can reverse into another function. In other words, if any function “f” takes x to y then, the inverse of “f” will take y to x.

RD Sharma Solutions for Class 12 Maths Chapter 4 – Inverse Trigonometric Functions

Chapter 4 of RD Sharma 12 Maths Solutions discusses the topic of the inverse of a function. Students will get to learn about the definition and meaning of inverse trigonometric functions, the inverse of the sine function, inverse of the cosine function, inverse of the tangent function, inverse of secant function, inverse of cosecant function, inverse of cotangent function, and properties of inverse trigonometric functions.

Inverse Trigonometric Functions: They are the inverse functions of the basic trigonometric functions such as sine, cosine, tangent, cotangent, secant, and cosecant functions. We can also term it as arcus functions, antitrigonometric functions or cyclometric functions.

Properties of Inverse Trigonometric Function

Property Set 1:

  • Sin−1(x) = cosec−1(1/x), x∈ [−1,1] − {0}
  • Cos−1(x) = sec−1(1/x), x ∈ [−1,1] − {0}
  • Tan−1(x) = cot−1(1/x), if x > 0 (or) cot−1(1/x) −π, if x < 0>
  • Cot−1(x) = tan−1(1/x), if x > 0 (or) tan−1(1/x) + π, if x < 0>

Property Set 2:

  • Sin−1(−x) = −Sin−1(x)
  • Tan−1(−x) = −Tan−1(x)
  • Cos−1(−x) = π − Cos−1(x)
  • Cosec−1(−x) = − Cosec−1(x)
  • Sec−1(−x) = π − Sec−1(x)
  • Cot−1(−x) = π − Cot−1(x)

Matrices: A rectangular array of m × n numbers (real or complex) in the form of m horizontal lines (called rows) and n vertical lines (called columns), is called a matrix of order m by n, written as m × n matrix.

Types of Matrices: The types of matrices are symmetric matrix, skew-symmetric matrix, Hermitian and skew-Hermitian matrix, orthogonal matrix, idempotent matrix, involuntary matrix, and nilpotent matrix.

Transpose of Matrix: The matrix which is obtained from a given matrix A by changing its rows into columns or columns into rows is known as the transpose of matrix A and is denoted by AT or A’.

Here, students can see the exercises explaining these concepts properly with solutions.
