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