The concepts for the preparation of mathematics for JEE Main & advanced should be chosen wisely to ensure that the requirements for each topic are fully met. Therefore, even if the priority of differential and integral calculus is undoubtedly the highest under any other chapter, calculus must be done according to trigonometry and algebra. Mathematics takes time and patience. Apart from that, there are many simple themes that can be prepared to get good grades in less time. But yes, the above may under no circumstances be skipped. Mathematics in JEE Main 2019 is again a scoring portion, but it is also the most protracted portion. Mathematics, therefore, requires the maximum input in terms of practice and effort. Therefore, the knowledge of important chapters for JEE Main 2019 mathematics is very important.

**Calculus:**Calculus comprises topics on functions, continuity, boundaries, differentiation, and application of derivatives, certain integrals, integration, and differential equations. All of the above topics are significant, and the Calculus unit covers around one-third of the question paper. So you must be well proficient with every single typical formula and method used in calculus.**Analytical Geometry:**The chapter is the simplest chapter under analytical geometry. The finest part around this section is that not many formulas are involved. The questions asked are usually based on simple basics and so students who have a good understanding of concepts can be raised in this chapter. Also, most students are very well acquainted with the concepts and nuances of this chapter, because it is also part of the class 10th syllabus.**Co-ordinate Geometry:**This topic is generally taught in high school, so that the aspirants are already aware of the rudimentary theories of the section, the equation of a line, etc. The solution of many problems subjectively and objectively from the coordinate geometry aids in scoring high in JEE.**Vectors (and 3D Geometry):**After you have practiced the part of the coordinate geometry, most of them will find the 3d geometry portion moderately simple and do well in this unit. It is principally simple-airy for the reason that JEE comprises of abundant problems allied with vectors that need standard formulas. This whole unit is known to be quite simple and the students usually randomly point at the problems of this topic compared to other topics. Especially the chapter on planes is quite simple and very scoring. The problems are relatively simple. This chapter is also largely an extension of the chapter on coordinate geometry. Therefore, it is quite easy to crack the problems of this chapter.**Permutations and Combinations and Probability:**These topics are very consistent, and the questions of them are the utmost stimulating and rational. Questions from these units are often asked and need a lot of practice and theory application.**Algebra:**The questions from Algebra are a bit hard, and most candidates find it hard with the units on arrangements and permutations and compound numbers. The exercise, on the other hand, is the key. The topic on complex numbers is contingent deeply on the coordinate geometry. Occasionally a hard question can be resolved from complex numbers if you can associate them sensibly with a coordinate geometry problem.**Trigonometry:**The formulas of trigonometry appear universally in JEE Math exam paper. Very few questions are created exclusively on trigonometry, but there are permanently questions that comprise normal trigonometric uniqueness. The significant feature of JEE math preparation is the memorization of customary formulas. Make sure you are completely through with them to escape nervousness during the last minute.

To ensure that students are well versed with these chapters, students should spend a lot of time in reading theory from at least one reliable source. Post-theory, students should practice as many problems as possible from many different sources. This will help you to capture as many different problems as possible. In addition, this is sure to improve your thought process and help you optimize your score.
