Top 4 Videos on Inverse Trigonometric Functions for Class 12 Core Mathematics by PW

Inverse Trigonometric Functions can be confusing when you need to find a principal value, determine a domain or range, or simplify an expression using the correct property. Two questions may look similar but require different approaches because inverse trigonometric functions have specific principal value ranges.

PW offers PW Class 12 Commerce Wallah videos that cover ITF at different stages of preparation. You can begin with trigonometry basics, study the chapter in detail, revise through a one-shot lesson, or combine ITF with Relations and Functions. These lessons help you practise common question types and strengthen your preparation for Class 12 Core Mathematics exams.

Video 1: Start ITF Preparation with Trigonometry Basics

This introductory Core Mathematics video revises the trigonometry concepts needed before studying ITF. It covers triangle ratios, standard values, identities, degree and radian systems, conversions, the ASTC rule, transformations, and radian-based questions before introducing sine graphs.

The video also outlines ITF domains, ranges, principal values, properties, graphs, practice questions, and homework, providing a starting point for further study.

Begin with this video if you need to strengthen your trigonometry basics before moving to inverse functions. Revise standard values, identities, and angle conversions first, then practise reading sine graphs.

A sound understanding of these topics can make it easier to approach domain-and-range questions and principal value problems in later lessons.

Video 2: Revise Relations, Functions and ITF Together

This combined revision video covers Relations and Functions alongside Inverse Trigonometric Functions. The Relations and Functions portion includes relation-based MCQs, geometric and divisibility relations, equivalence classes, function examples, and rational and quadratic problems.

The ITF section revisits domains, ranges, principal values, graphs, properties, and simplification. Step-by-step numerical problems and exam-focused questions support NCERT revision across both chapters.

Choose this video if you want to revise the first two Class 12 Core Maths chapters together. It helps you switch between function concepts and ITF problems while reviewing different question formats.

Use it after studying both chapters, and note which topics require separate practice before your school tests or board exams.

Video 3: Understand ITF Graphs, Principal Values and Properties in Detail

This detailed video explains inverse functions and the need for domain restrictions before covering the domains, ranges, principal value branches, and graphs of the main inverse trigonometric functions.

It also includes graph-based questions, property applications, range problems, substitution methods, and additional domain-and-range practice. NCERT questions, previous-year questions, competency-based tasks and a chapter summary help you revise concepts and practise exam-style problems.

Use this video if you need a more detailed explanation before attempting chapter exercises. Focus on how graphs and principal value branches help determine the correct answer.

Once you understand the worked examples, solve similar questions without referring to the solutions to check your understanding and improve accuracy.

Video 4: Revise the Complete ITF Chapter with a One-Shot Lesson

This one-shot video begins with Class 10 and Class 11 trigonometry basics before covering sine and cosine graphs, invertibility, angle restrictions, inverse functions, and principal value ranges. It also includes a domain-and-range table, important properties, graph-based questions, shortcut methods, and practice problems.

The focus on CBSE and NCERT concepts makes the lesson useful for revising the chapter and preparing for Class 12 previous-year questions.

Use this video when you have studied ITF and want to revisit the main concepts in one session. Pay particular attention to principal value ranges and the conditions under which an inverse function is defined. Practise the examples independently to improve your ability to select the correct property and solve board-style questions accurately.

After watching the videos, practise questions on domains and ranges, principal values, graphs, and simplification. Write down the properties you tend to forget and revisit the questions you answer incorrectly.

Regular practice alongside these PW videos can help you improve accuracy and prepare more effectively for your Class 12 Core Mathematics board exams.
