NCERT Solutions Class 12 Mathematics Chapter 2 requires students to use their critical thinking ability and apply a wide range of formulas they have learnt.
2.1 Introduction
This chapter on Inverse trigonometric functions is crucial in higher-grade Mathematics for many engineering and science streams as it builds the fundamentals of calculus. Inverses of trigonometric functions exist to overcome the restrictions we have on domains and their respective ranges. To solve inverse trigonometric functions, one must first understand the trigonometric ratios. The behaviour of the trigonometric functions is usually demonstrated via graphical methods.
2.2 Basic Concepts
This section will quickly revise the corresponding invertible functions. In addition, you will obtain a precise understanding of the functions of graphs and integers. Students will understand the concept that the graph of an inverse function can be extracted from the correlated graph of the original function as a mirror image.
It will develop a better understanding between the domain and the co-domain. The domains are correlated to the principles of functions. This segment will help the students find the unknown angle’s value. Inverse sine and inverse cosine are essential to study. And their basics and root concepts are mentioned in this segment.
2.3 Properties of Trigonometry
This section will cover various essential properties of inverse trigonometric functions. These are the inverse functions of sine, cosine, tangent, cotangent, secant, and cosecant with restricted domains. It would teach students the properties and relationships that exist between various trigonometric functions via formulas.
Few of the formulas covered in the NCERT Solutions for Class 12 Mathematics chapter 2 are given below:
- sin-1 (–x) = – sin-1 x
- tan-1 x + cot-1 x = π/2
- sin-1 x + cos-1 x = π/2
- cos-1 (–x) = π – cos-1 x
- cot-1 (–x) = π – cot-1 x
Students should also refer to additional study resources such as Extramarks short chapter notes and solved solutions for NCERT Exemplars.
