# GCSE Maths Formula Sheet: Essential Equations for Success

The **GCSE Maths formula sheet Edexcel Foundation and Higher** levels provide a comprehensive collection of essential mathematical formulas. This page serves as a quick reference guide for students preparing for their **Edexcel GCSE Maths** exams, covering a wide range of topics from basic geometry to more advanced trigonometry and algebra.

**Highlight**: This formula sheet is an invaluable resource for both Foundation and Higher tier students, containing all the key formulas needed for the **Edexcel GCSE Maths** exam.

The sheet begins with area formulas for common shapes. Students can find equations for calculating the areas of rectangles (l × w), parallelograms (b × h), triangles (½ × b × h), and trapeziums (½(a + b)h). These formulas are fundamental for solving geometry problems in the exam.

Next, the sheet covers compound measures, which are crucial for physics-related questions. It includes formulas for speed (distance ÷ time), density (mass ÷ volume), and pressure (force ÷ area). Understanding these relationships is essential for tackling real-world application problems.

**Definition**: Compound measures are quantities that are derived from two or more other quantities, often expressed as ratios or products.

The volume section provides formulas for calculating the volume of cuboids (l × w × h), prisms (area of cross-section × length), cylinders (πr²h), and pyramids (⅓ × area of base × height). These are particularly important for spatial reasoning questions and 3D geometry problems.

**Example**: To find the volume of a cylinder with radius 5 cm and height 10 cm, you would use the formula V = πr²h, giving V = π × 5² × 10 ≈ 785.4 cm³.

Circle geometry is another key topic, with formulas provided for circumference (πd or 2πr) and area (πr²). The sheet also includes a helpful diagram of a circle, labeling key parts such as radius, diameter, and circumference.

For algebra, the quadratic formula is prominently displayed. This formula, x = [-b ± √(b² - 4ac)] ÷ 2a, is essential for solving quadratic equations in the form ax² + bx + c = 0.

**Vocabulary**: The quadratic formula is used to find the roots (solutions) of a quadratic equation, where a, b, and c are the coefficients of the equation ax² + bx + c = 0.

Lastly, the sheet covers trigonometric formulas, including the basic ratios of sine, cosine, and tangent, as well as the more advanced sine and cosine rules. These are crucial for solving problems involving triangles, especially when not all sides or angles are known.

**Quote**: "Sine rule: a ÷ sin A = b ÷ sin B = c ÷ sin C"

This **GCSE Maths formula sheet PDF** is an essential tool for exam preparation, covering all the key formulas needed for the **Edexcel GCSE Maths** curriculum. Students should familiarize themselves with these formulas and practice applying them to various problem types to ensure success in their exams.
