CBSE Class 9 Maths Important Formulas Used in RD Sharma Solutions

1. Number Systems

• a^m × aⁿ = a^m+n
• a^m / aⁿ = a^m−n
• (a^m)ⁿ = a^mn
• a⁰ = 1 (for a ≠ 0)
• a^-n = 1 / aⁿ

2. Polynomials & Algebraic Identities

• (a + b)² = a² + 2ab + b²
• (a − b)² = a² − 2ab + b²
• (a + b)(a − b) = a² − b²
• (a + b + c)² = a² + b² + c² + 2ab + 2bc + 2ca
• (a + b)³ = a³ + 3a²b + 3ab² + b³
• (a − b)³ = a³ − 3a²b + 3ab² − b³
• a³ + b³ = (a + b)(a² − ab + b²)
• a³ − b³ = (a − b)(a² + ab + b²)

3. Linear Equations in Two Variables

• General form: ax + by + c = 0
• Solution: Any pair (x, y) that satisfies the equation

4. Coordinate Geometry

• Distance: √[(x₂−x₁)² + (y₂−y₁)²]
• Midpoint: ((x₁+x₂)/2, (y₁+y₂)/2)

5. Triangles

• Area = 1/2 × base × height
• Heron’s formula: √[s(s−a)(s−b)(s−c)], where s = (a+b+c)/2

6. Quadrilaterals

• Sum of angles = 360°
• Area of parallelogram = base × height
• Area of rectangle = length × breadth
• Area of square = side²

7. Circles

• Circumference = 2πr
• Area = πr²
• Length of arc = (θ/360) × 2πr
• Area of sector = (θ/360) × πr²

8. Surface Area and Volume

• Cube: Surface Area = 6a², Volume = a³
• Cuboid: Surface Area = 2(lb + bh + hl), Volume = l × b × h
• Cylinder: Surface Area = 2πr(h + r), Volume = πr²h
• Cone: Surface Area = πr(l + r), Volume = (1/3)πr²h
