I am so weak in Trigonometry, Can i am not able to score good in JEE Mains Maths paper.

Important topics in JEE Main Maths are as follows-



Calculus

Co-ordinate Geometry

Vectors (and 3D Geometry)

Algebra

Trigonometry



You can refer S.L Loney to prepare for Trigonometry.



The formulae of trigonometry appear everywhere in JEE Mathematics exam paper. Very few questions are purely based on trigonometry, but there are always questions that involve standard trigonometric identities. Remember that an important aspect of the JEE Mathematics preparation is memorizing standard formulae. Make sure you are thorough with them to avoid last-minute anxiety



You can solve past year problems and MCQs related to Trigonometry.



Trigonometry concepts are used in other calculus coordinate geometry etc. so, you can't ignore this chapter.



Practice and practice more for trigonometry you will able to crack it.
