This course provides a clear and structured introduction to trigonometry, specifically designed for GCSE students. We'll demystify the relationships between angles and sides in right-angled triangles, exploring the core trigonometric ratios: sine, cosine, and tangent. Through engaging explanations, worked examples, and plenty of practice, you'll master the art of applying SOHCAHTOA to calculate unknown sides and angles. What You'll Learn: Understanding Right-Angled Triangles: We'll begin by revisiting the properties of right-angled triangles, identifying the hypotenuse, opposite, and adjacent sides relative to a given angle. Introducing SOH CAH TOA: You'll learn the mnemonic SOH CAH TOA and understand how it relates to the sine, cosine, and tangent ratios. We'll break down each ratio, explaining its formula and how it connects to the sides of a right-angled triangle. Calculating Sides and Angles: Using SOH CAH TOA, you'll learn to calculate the lengths of unknown sides when given an angle and another side. You'll also discover how to determine the size of an unknown angle when given two sides. Problem Solving: We'll tackle a variety of GCSE-style problems, applying your knowledge of SOH CAH TOA to real-world scenarios and building your confidence in tackling different question types. Step-by-Step Examples: Each concept will be reinforced with clear, step-by-step worked examples, demonstrating the application of the formulas and problem-solving strategies. Practice Exercises: Throughout the course, you'll have opportunities to practice your skills with a range of exercises, allowing you to solidify your understanding and identify areas where you might need further support. Teaching Style: My teaching style is patient, supportive, and interactive. I believe in breaking down complex concepts into manageable chunks and providing ample opportunities for practice. I encourage questions and create a relaxed learning environment where students feel comfortable participating.
Learning Goals
Students will be able to confidently apply the sine, cosine, and tangent ratios (SOHCAHTOA) to calculate unknown side lengths and angle measures in right-angled triangles.
Students will be able to solve a variety of problems involving right-angled triangles, including real-world applications, by strategically using trigonometric ratios and the Pythagorean theorem.
Other Details
Pre-Requisites
A basic understanding of geometric shapes, particularly triangles, is essential. Students should know what a right angle is and be familiar with the Pythagorean theorem (a² + b² = c²).
