### 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 |

### RD Sharma Solutions for Class 12 Maths Chapter 2 – Functions

Chapter 2, Functions of RD Sharma Class 12 Maths, gives an account of various topics such as the definition of functions, function as a correspondence, function as a set of ordered pairs, the graph of a function, vertical line test, constant function, identity function, modulus function, greatest integer function, properties of greatest integer function, smallest integer functions and its properties, fractional part function, signum function, exponential function, logarithmic function, reciprocal and square root function, square function, square root function, cube function, reciprocal squared function, operations on real function, kinds of functions such as one-one, many-one and onto function, bijection, the composition of functions and its properties and composition of real functions. 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 3 – Binary Operations

In Chapter 3 of the RD Sharma textbook, we shall see the definition of a binary operation, the number of binary operations, types of binary operations such as commutativity, associativity and distributivity, an identity element, inverse of an element, composition table, addition modulo ‘n’ and multiplication modulo ‘n’.

**Binary Operations:** It is defined as an operation * which is performed on a set A. The function is given by *: A * A → A. So, the operation ***** performed on operands *a* and *b* is denoted by **a * b****.**

**Types of Binary Operations: **The types of Binary Operations are Distributivity, Associativity, and Commutativity.

### 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)

### RD Sharma Solutions for Class 12 Maths Chapter 5 – Algebra of Matrices

Chapter 5 of the RD Sharma textbook starts with the definitions of Matrices. Students go on to learn about types of matrices, equality of matrices, the addition of matrices, properties of matrix addition, multiplication of a matrix by a scalar, properties of scalar multiplication, subtraction of matrices, multiplication of matrices, properties of matrix multiplication, positive integral powers of a square matrix, transpose of a matrix, properties of transpose, symmetric and skew-symmetric matrices via examples.

**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.
