ICSE Class 9 Mathematics Books, Chapters & PDF Downloads

ICSE Class 9 Mathematics is a crucial bridge between middle school arithmetic and the more advanced algebra, geometry, mensuration, trigonometry, and statistics of higher classes. At this stage, students learn how to handle complex numbers, equations, formula-based problems, reasoning-based geometry, and graphical representation of data. This page brings together all chapter-wise PDFs for ICSE Class 9 Mathematics (including Arun Self Help / Arun Deep and other reference books) in one place, so students can revise each concept systematically.

Each chapter PDF contains theory, worked examples, practice exercises, and exam-oriented questions. Topics such as Rational and Irrational Numbers, Compound Interest, Factorisation, Linear Equations, Triangles, Area and Perimeter, Statistics, Mensuration, and Trigonometry are covered in depth. Students can download individual chapters and use them for daily homework, revision, and ICSE board foundation building.

Important Formulas for ICSE Class 9 Mathematics

Here are some of the most important formulas from the Class 9 Mathematics chapters, presented in a clean list for quick revision.

  • \( \text{Compound Interest (amount)}: \ A = P \left(1 + \frac{r}{100}\right)^n \)
  • \( \text{Simple Interest}: \ SI = \frac{P \times R \times T}{100} \)
  • \( (a + b)^2 = a^2 + 2ab + b^2 \)
  • \( (a – b)^2 = a^2 – 2ab + b^2 \)
  • \( a^2 – b^2 = (a – b)(a + b) \)
  • \( \text{Quadratic factorisation example}: \ ax^2 + bx + c = a(x – \alpha)(x – \beta) \)
  • \( \text{Indices laws}: \ a^m \times a^n = a^{m+n}, \ \frac{a^m}{a^n} = a^{m-n}, \ (a^m)^n = a^{mn} \)
  • \( \log_{10} (ab) = \log_{10} a + \log_{10} b \)
  • \( \log_{10} \left(\frac{a}{b}\right) = \log_{10} a – \log_{10} b \)
  • \( \log_{10} a^n = n \log_{10} a \)
  • \( \text{Pythagoras theorem}: \ a^2 + b^2 = c^2 \)
  • \( \text{Perimeter of rectangle}: \ P = 2(l + b) \)
  • \( \text{Area of rectangle}: \ A = l \times b \)
  • \( \text{Area of triangle}: \ A = \frac{1}{2} \times b \times h \)
  • \( \text{Circumference of circle}: \ C = 2\pi r \)
  • \( \text{Area of circle}: \ A = \pi r^2 \)
  • \( \text{Surface area of cuboid}: \ SA = 2(lb + bh + hl) \)
  • \( \text{Volume of cuboid}: \ V = l \times b \times h \)
  • \( \text{Volume of right circular cylinder}: \ V = \pi r^2 h \)
  • \( \sin^2 \theta + \cos^2 \theta = 1 \)
  • \( \tan \theta = \frac{\sin \theta}{\cos \theta} \)
  • \( \text{Distance formula}: \ d = \sqrt{(x_2 – x_1)^2 + (y_2 – y_1)^2} \)
  • \( \text{Mean of data}: \ \bar{x} = \frac{\sum x_i}{n} \)
  • \( \text{Median position for odd } n: \ \frac{n+1}{2} \)
