## FAQs on ICSE Class 9 Mathematics Revision Notes

1. How Many Chapters are There in ICSE Class 9 Mathematics Syllabus?

The ICSE class 9 mathematics syllabus is quite vast, consisting of 8 topics which are further divided into 28 chapters(approximately), such as:

Pure Arithmetic: This topic consists of rational and irrational numbers.

Commercial Mathematics: This includes compound interest (with and without using formula).

Algebra: It consists of expansions, factorisation, solving simultaneous linear equations in two variables. (with numerical coefficients only), and Indices/ Exponents.

Geometry: It includes triangles, Pythagoras theorem, rectilinear figures, circles.

Statistics: This topic includes an introduction, collection of data, presentation of data, graphical representation of data, mean, median of ungrouped data.

Mensuration: It consists of the area and perimeter of a triangle, area and circumference of a circle, surface area and volume of cube and cuboids.

Trigonometry: Trigonometric ratios, simple 2-D problems involving one right-angled triangle, the concept of trigonometric ratios of complementary angles and their direct application.

Coordinate Geometry: This topic has several subtopics included like cartesian system, plotting of points in the plane for given coordinates, solving simultaneous linear equations in 2 variables graphically and using the distance-section formula in finding the distance between two points.

2. What are the Essential Chapters of ICSE Class 9 Mathematics Revision Notes?

The critical chapters of ICSE class 9 Mathematics revision notes are:

Simultaneous Linear Equation - The essential thing which must be kept in mind while answering questions on this topic is plotting the points correctly. Moreover, it is easy and scoring.

Logarithm - There are various laws in this chapter, which can be used in solving different expressions/equations, including exponents. Enough problems of logarithm should be solved, to get a grip over it.

Mid-Point Theorem - The mid-point theorem and its converse, along with the intercept theorem is used in solving many problems of triangles, quadrilaterals, etc.

Area Theorem - The theorems of this chapter are useful in the mensuration chapter when finding areas of figures of different types of triangles/quadrilaterals.

Circle - The properties of a circle, theorems, and formulae of this topic are critical. Solving a variety of questions on this topic helps you to revise the previous cases.

Rectilinear Figures - The problems from this chapter are less time consuming and easy. This topic should not be skipped.

Statistics (Including Mean and Median) - In class 9 ICSE, it is highly weighted and easy. The topic is continued in higher classes and is itself an independent subject with great applications.

Trigonometry - It is also a heavily weighted part of the exams. The central part of studying in this topic are trigonometric ratios and the relationship between trigonometric ratios and trigonometric values.

3. Can ICSE Class 9 students find the revision notes of all the Maths chapters together in one place?

The ICSE Class 9 students can find the revision notes of all the Maths chapters together at one place on the official website of Vedantu. There will be a list of all the chapters on the webpage of Vedantu. From that list, students can select the chapters they want and can download the notes by clicking the option of ‘Download PDF'. These notes are very useful as it covers all the concepts of the chapter in short. These notes save lots of time for the students at the time of revision during the examination.

4. How to get full marks in the ICSE Class 9 Mathematics examination?

Mathematics is an application-based subject in which students have to use their calculative and logical skills to solve questions because of this reason most of the students find this subject a difficult one. But with the use of the right study materials and proper study strategies, they can easily score well in the Class 9 Mathematics examination. Working out on the sample papers and previous years question papers will assist them in doing self-evaluation and knowing the exam structure. The revision notes will prove to be fruitful in remembering all the formulas and important key points during the examination.

5. Which textbooks are recommended for the ICSE students of Class 9 for studying all the Maths chapters?

The experts recommend the textbooks of the Selina publications for the ICSE students of Class 9 for studying all the Maths chapters. These books help in understanding and learning all the important concepts of the chapters. As it is very important to attempt questions in all the essential steps, therefore by practising these books students will learn to answer the questions in all the required steps. These books boost confidence in students and assist them in completing their courses on time. Students can also prepare for the competitive exams from these books. These books provide revision notes and several questions for practice.
