Class 12 Basic Mathematics Inverse Circular Functions Solution and Guide

The topic of inverse circular functions is an essential part of Class 12 Basic Mathematics. It builds upon the foundation of trigonometry and introduces students to the concept of reversing trigonometric functions. This topic is not only important for NEB examinations but also for understanding advanced mathematical concepts in calculus and beyond. To help students navigate this subject, we have created a detailed Inverse Circular Functions Solution and Guide.

This guide is based on the Class 12 Basic Mathematics textbook approved by the Curriculum Development Center of Nepal. It is designed to simplify complex concepts, provide clear explanations, and offer step-by-step solutions to exercises.

Inverse circular functions are the inverses of standard trigonometric functions like sine, cosine, and tangent. These functions allow us to determine the angle when the value of the trigonometric ratio is given. For example, ${\sin }^{-1}(x)$ represents the angle whose sine is $x$. Similarly, the guide covers the inverse of cosine (${\cos }^{-1}(x)$), tangent (${\tan }^{-1}(x)$), cotangent (${\cot }^{-1}(x)$), secant (${\sec }^{-1}(x)$), and cosecant (${\csc }^{-1}(x)$).

The guide provides:

1. Definitions and Properties:

   • Domain and range of inverse circular functions.
   • Principal value branch for defining these functions.
   • Graphical representation to visualize the functions.

2. Solved Examples:
   Step-by-step solutions to textbook problems, explaining how to compute the inverse functions and apply their properties in calculations.

3. Applications:

   • Solving trigonometric equations involving inverse functions.
   • Simplifying expressions with combinations of trigonometric and inverse trigonometric functions.
   • Real-world scenarios like measuring angles in navigation and engineering.

4. Practice Problems:
   A set of additional problems for self-study and practice to strengthen understanding.

This guide also includes tips for handling tricky problems and avoiding common mistakes students make while dealing with inverse functions.

To make learning more accessible, we have provided a downloadable PDF of the guide in this article. Students can use this resource to complete assignments, prepare for exams, and gain a thorough understanding of inverse circular functions. Sharing the guide with classmates can enhance collaborative study sessions.

The  Inverse Circular Functions Solution and Guide is tailored to help students excel in this topic with confidence. Download the guide today, share it with your friends, and start mastering inverse circular functions in preparation for your NEB examinations!
