 # IIT JEE Mathematics Important Topics for JEE Exams Mathematics is the foundation of complex engineering calculations. In JEE exams, most of the questions asked in the Mathematics section are generally based on the formulas and their applications. You need to practice a lot for scoring well in this section. The more problems you will solve, the better will be your speed and accuracy. It would be impossible to score by just memorizing and reading formulas in mathematics. Try to master all the key concepts by visualizing and apply them to the real word problems.

In JEE, there are a lot of chapters included in Mathematics syllabus and unlike Chemistry or Physics, there is nothing called less important or very important in mathematics as most of the chapters are interlinked. Therefore you can’t skip any particular section to focus more on any other section.

## JEE Mathematics Syllabus

The JEE syllabus for mathematics broadly consists of the following six topics:

1. Calculus: This unit very crucial for both JEE Main and JEE Advanced mainly because of its vastness and the level of difficulty. In every engineering Entrance Examination, you could expect several numbers of questions from this unit. You don’t have to worry much about JEE Mathematics if you develop a stronghold in this unit, therefore, you need to practice and prepare well for this unit. Important subtopics included in calculus are Limits, Differentiability Continuity, Relationship between Continuity & Differentiability, Differentiation, Integration, Definite Integrals, Integration by Parts, properties of definite integrals, Rate Measurement, Tangents and Normal, Maxima and Minima, Differential Equations and Area under curves.

2. Co-ordinate Geometry: This unit is all about understanding some geometrical shapes like circles, parabola, hyperbola and more. Questions from this unit are generally based on the application of formulas which makes it quite interesting and for most of the students it is a high scoring unit. You can fetch maximum marks from this section. Focus more on Parabola, Circle, Ellipse, straight lines and Hyperbola. Among all these Straight Lines and Circles are the most important ones.

3. 3D Geometry and Vectors: This unit is quite complex and conceptual. Its weightage in JEE is somewhat similar to Coordinate Geometry. It also includes complex numbers along with some parts of geometry. You can easily score well from this section if you understand certain complex concepts of vectors and 3D properly. Try to develop a stronghold on basics and focus more on understanding this unit through visualization.

4. Algebra: This unit is quite interesting and certain important topics like Logarithms, Matrices and Determinants and Quadratic Equations are quite easy to understand and are among the favourites for many students. Several times in JEE Main and Advanced there were few questions from Complex Number merged with the vectors. In JEE Advanced, you can expect a passage type question from matrices and determinants and it might be the easiest one to answer. You can also expect a few conceptual questions from Permutations and Combinations. Formula-based questions are generally asked from Sequence and Series and Binomial Theorem. Therefore, by avoiding silly mistakes you could easily score good marks from this portion.

5. Trigonometry: It is one of the most important topics for JEE Main. Inverse Trigonometry, Trigonometric functions, and trigonometric ratios are some of the most imperative topics where you need to focus on. Since several numbers of questions are asked from this unit, therefore, getting the knack of some basic trigonometric concepts could surely benefit a JEE aspirant. For scoring well in this section you need to memorize all the trigonometric formulas along with their graphs and substitutions.

Now, let’s take a look at JEE Mathematics section 2019 that includes important topics for JEE Main (Paper 1) and JEE Advanced (Paper 1 and 2).

### JEE Main 2019 Maths Section

The maths section in JEE Main 2019 exam had questions that were set on a moderate level. However, this section had problems that needed calculations and candidates found that it took a longer time than usual to solve all the questions. On breaking up the number of questions and the topics they were based on, algebra had 9 questions, coordinate geometry had 8 questions, calculus had 9 questions and there 4 questions as from probability, mathematical reasoning and statistics respectively. In terms of difficulty, 4 questions were difficult, 13 were on a moderate level and another 13 questions were easy.

Let us look at the topic wise distribution of questions and weightage of marks below.

### JEE Advanced 2018 Maths Section

The maths section in JEE Advanced 2018 question paper was on a moderate to difficult level. In paper 1 the mathematics section had questions that were concept-based and tricky. There were 16 questions set from the 12th standard syllabus. Paper 2 consisted of questions that were more formula based and conceptual. 6 questions came from the 11th standard syllabus and 12 questions were asked from the 12th standard syllabus.
