Trigonometry for JEE Advanced Preparation: Check tips to prepare for trigonometry

Read the article below to check important tips for the good preparation of JEE Advanced Trigonometry.

JEE Advanced requires you to be smart in your preparation as well as in the way that you solve the exam paper. Even after knowing everything, a lot of aspirants mess things up during the exam either due to pressure or poor time management. One needs to know the set of chapters that should be attempted first. Time management should be done very carefully in mathematics especially because the paper is generally lengthy or too tough, but scoring at the same time. Trigonometry is one such chapter that can possibly fetch you easy marks if done with proper logic and care. You can attempt questions from this chapter earlier and also, do try option elimination first when you see the questions from trigonometry.

Classifications in Trigonometry

Trigonometry consists of a few broad topics. They are generally given as separate chapters in almost all books of JEE Advanced mathematics, or trigonometry specifically. These topics are:

1. Trigonometric functions and identities: This chapter consists of the basic trigonometric functions, their curves and their applications. The chapter explains all the identities formed with these functions along with their applications. It is the first step to understanding trigonometry, and finally using it to solve complex problems.
2. Trigonometric equations: This chapter involves solving trigonometric equations. The chapter consists of the general solutions to all the trigonometric functions. Problems in this chapter are a bit tricky at times.
3. Heights and Distances: This chapter is a small one but consists of the actual application of all that you learn in the above two chapters. This chapter has word problems that are interesting to solve and can be easily correlated with real-life scenarios.
4. Inverse Trigonometric functions: This chapter is very different from the above chapters and forms a larger part of trigonometry. It consists of the inverse of the functions that were taught to you in the first lesson. Problems in this chapter are asked frequently in JEE.
5. Solutions and Properties of Triangles: This chapter has a lot of properties that you would need to remember, and for this reason, the chapter gets very complicated at times. The chapter involves the application of concepts that you learned in the basic chapters of trigonometry. Do stick to the syllabus while you study this chapter as studying excessive properties might make you forget the useful ones.

How to Prepare Trigonometry for JEE Advanced

The first step to preparing trigonometry for JEE Advanced involves choosing the correct books for the same. You could use any of the following books to prepare trigonometry for JEE Advanced:

You should start with basic theory and then do a lot of solved examples in order to understand concept application. Once that is done, do a lot of JEE Main level problems to gain confidence and command over the topic. Do the chapters in the order given in the book. Once you are done with the Main level problems, do a good number of JEE Advanced level problems of varying types. Don’t let any doubt remain in your mind and clear all the doubts with your teachers. You must know the curves of all the trigonometric as well as the inverse trigonometric functions. You should know the transformations that can be applied in the same. Remembering formulas is of utmost importance in trigonometry. You can note down the formulas in one place and then see them on a weekly basis to keep them in your mind always.
