Let’s talk about Inverse Trigonometry some more:

RS Aggarwal Class 12 Solutions Chapter 4 Inverse Trigonometry

Inverse trigonometry is the opposite of the basic trigonometric functions, such as sine, cosine, tangent, cotangent, etc. You can also call these functions “arc functions” or “anti-trigonometric functions.” With the help of trigonometric ratios, these functions are used to find the angles. In the fields of engineering, geometry, and navigation, these functions are used a lot.

These functions are also known as “arc functions” because they calculate the arc length for any given trigonometric value. Inverse trigonometry is mostly used to do the opposite of what basic trigonometric functions do. The answers explain the basics of how inverse trigonometric functions work. It tells the reader how to use the formula in the chapter.

There are six formulas for inverse trigonometry. They are:

  • Arcsine : sin-1(-x) = -sin-1(x), x ∈ [-1, 1]
  • Arccosine : cos-1(-x) = Ï€ -cos-1(x), x ∈ [-1, 1]
  • Arctangent : tan-1(-x) = -tan-1(x), x ∈ R
  • Arccotangent : cot-1(-x) = Ï€ – cot-1(x), x ∈ R
  • Arcsecant : sec-1(-x) = Ï€ -sec-1(x), |x| ≥ 1
  • Arccosecant : cosec-1(-x) = -cosec-1(x), |x| ≥ 1

Detailed discussion of RS Aggarwal solutions for Class 12 Chapter 4 Inverse Trigonometric Functions

This course will teach you how to find the fundamental values of the inverse trigonometric functions given in the initial exercises.

  • In the third and fourth exercises, you’ll need to prove some equations involving these functions.
  • With the help of the basic properties, you will learn new properties and how to prove them in the exercises.
  • In the fourth exercise, you will have to draw the graphs of different inverse trigonometric functions.
  • The practise questions include both easy and hard ones for the RS Aggarwal Class 12 Solutions board exams and other important national-level entrance exams.
  • The answers are written so that they cover all the important topics and are easy to understand.

FAQ ( Frequently Asked Questions )

1. What is an inverse trigonometric function, and how does it work?

Ans – Inverse trigonometry is the opposite of the basic trigonometric functions, such as sine, cosine, tangent, cotangent, etc. They are also called the arc functions, anti trigonometric functions, and cyclometric functions. When you do the opposite of trigonometric functions, you get the length of the arc that is needed to get the value you want.

With the help of trigonometric ratios, these functions are used to find the angles. In the fields of physics and navigation, these functions are used all the time. When you know the lengths of two sides of a right triangle, you can use the six important functions to find the lengths of the angles.

2. What are all six inverse trigonometric functions and formulas?

Ans – Arcsine, Arccosine, Arctangent, Arccotangent, Arcsecant, and Arccosecant are the six inverse trigonometric identities or functions. These functions are used a lot in engineering, physics, geometry, and other fields.

Here are the main formulas for inverse trigonometry:

  • Arcsine : sin-1(-x) = -sin-1(x), x ∈ [-1, 1]
  • Arccosine : cos-1(-x) = Ï€ -cos-1(x), x ∈ [-1, 1]
  • Arctangent : tan-1(-x) = -tan-1(x), x ∈ R
  • Arccotangent : cot-1(-x) = Ï€ – cot-1(x), x ∈ R
  • Arcsecant : sec-1(-x) = Ï€ -sec-1(x), |x| ≥ 1
  • Arccosecant : cosec-1(-x) = -cosec-1(x), |x| ≥ 1

3. From where I can download RS Aggrawal Class 12 solutions Chapter 4 ?

Ans –  Students can get RS Aggarwal Class 12 Solutions Chapter 4 Trigonometric functions from the Utopper website or app. The experts who put together these solutions for Class 12 Mathematics know a lot about the subject and can help students prepare better for their exams.

4. How many exercises are in RS Aggrawal Class 12 Solutions Chapter 4?

Ans – This chapter is longer than the ones that came before it in RS Aggarwal Class 12 Solutions Chapter 4. In Chapter 4 of Class 12 Math, “Inverse of Trigonometric Functions,” there are a total of 126 questions spread across 5 exercises. These questions are meant to help students fully understand the chapter’s ideas and review what they’ve learned. In the first set of exercises, students learn about the values of inverse trigonometric functions. In later exercises, they learn about different proofs and properties of inverse trigonometric functions. 

5. What are the Identities of Inverse Trigonometric Function ?

Ans – Inverse trigonometric functions have the following :

  • sin-1 (sin x) = x provided –π/2 ≤ x ≤ Ï€/2
  • cos-1 (cos x) = x provided 0 ≤ x ≤ Ï€
  • tan-1 (tan x) = x provided –π/2 < x < Ï€/2
  • sin(sin-1 x) = x provided -1 ≤ x ≤ 1
  • cos(cos-1 x) = x provided -1 ≤ x ≤ 1
  • tan(tan-1 x) = x provided x ∈ R
  • cosec(cosec-1 x) = x provided -1 ≤ x ≤ ∞ or -∞ < x ≤ 1
  • sec(sec-1 x) = x provided 1 ≤ x ≤ ∞ or -∞ < x ≤ 1
  • cot(cot-1 x) = x provided -∞ < x < ∞
  • sin^(-1) = (2x)/(1 + x^2) = 2 tan^{-1}x
  • cos^(-1) = (1 – x^2)/(1 + x^2) = 2 tan^{-1}x
  • tan^(-1) = (2x)/(1 – x^2) = 2 tan^{-1}x
  • 2cos-1 x = cos-1 (2×2 – 1)
  • 2sin-1x = sin-1 2x√(1 – x2)
  • 3sin-1x = sin-1(3x – 4×3)
  • 3cos-1 x = cos-1 (4×3 – 3x)
  • 3tan-1x = tan-1((3x – x3/1 – 3×2))
  • sin-1x + sin-1y = sin-1{ x√(1 – y2) + y√(1 – x2)}
  • sin-1x – sin-1y = sin-1{ x√(1 – y2) – y√(1 – x2)}
  • cos-1 x + cos-1 y = cos-1 [xy – √{(1 – x2)(1 – y2)}]
  • cos-1 x – cos-1 y = cos-1 [xy + √{(1 – x2)(1 – y2)}
  • tan-1 x + tan-1 y = tan-1(x + y/1 – xy)
  • tan-1 x – tan-1 y = tan-1(x – y/1 + xy)
  • tan-1 x + tan-1 y +tan-1 z = tan-1 (x + y + z – xyz)/(1 – xy – yz – zx)
