What to Learn in Trigonometry for JEE Main

by Hanery Scott

Students who dream of studying engineering at IITs should clear the JEE Main and JEE Advanced exams. In 2022, the JEE Main will be conducted in two sessions. Session 1 was held in June, and session 2 will be held in July. Clearing the JEE Main and the JEE Advanced is really a tough task since the competition is very high. It needs dedication, hard work and proper planning to crack the JEE exams. Students are recommended to work hard to ensure a seat at IIT.

As far as the JEE exam is concerned, having a strong knowledge of trigonometric functions is important. 2-3 questions can be expected from this topic for any engineering entrance exam. Trigonometry is a topic with a number of formulas and identities. Students must learn these identities, formulas, and tricks of trigonometric functions and inverse trigonometric functions. They should be thorough with the topic so that they can easily apply the formulas where required. In this article, we will discuss what the important topics in coordinate geometry and trigonometric functions are.

Important Topics in Trigonometry for JEE

When we talk about trigonometric functions, we can say that the following topics are very important from the exam point of view. Students should learn the trigonometric ratios, graphs of these functions, identities, half angle formulas, sum and difference identities, reciprocal identities, inverse trigonometric formulas, etc. Students should byheart these formulas so that they can solve the problems in a faster manner. If they are thorough with the basics and formulas, they need not waste time thinking about how to crack the problems. So they are advised to have a thorough understanding of the trigonometric functions and formulas.

 

Students should also learn the values of the trigonometric functions at different angles. This will help them to save their precious time during the exams. Students can expect questions from heights and distances which use trigonometric functions.

Importance of distance formula

As far as the JEE Main is concerned, coordinate geometry has much importance. Students can easily score on this topic if they learnt in the proper manner. We use the distance formula for finding the distance between two points in coordinate geometry. Consider two points, A(x1, y1) and B(x2, y2). Then we can say that the distance between A and B is given by AB = √((x2-x1)2+(y2-y1)2). Students can expect at least one question which uses this formula. So they must learn this formula properly and solve more problems with it.

Students are recommended to revise and learn previous years’ questions on trigonometric functions and coordinate geometry. They should make short notes of these topics since it has several identities and formulas. They can use these important formulas notes during the last-minute revision. Chapter-wise JEE Main and JEE Advanced questions on coordinate geometry are also available online. Students should make use of these questions and practice them for the entrance exam.
