Sine & Cosine - Friendly Guide to the Unit Circle

Hey there! 👋 Welcome to the channel of VitoshAcademy! 🌟 🎨 Ever wondered how sine and cosine work and why they are so important in mathematics? In this video, we will break it all down step by step, using clear visuals, Python code, and animations to help you understand it. 🧠 What You'll Learn: 🔹 The geometric definition of sine and cosine using the unit circle. 🔹 How sine and cosine map angles to coordinates (x = cos θ, y = sin θ). 🔹 Exact values for key angles like 30°, 45°, and 60°, visualized with labeled triangles. 🔹 The symmetry of sine and cosine across all four quadrants. 🔹 The Pythagorean identity: cos²θ + sin²θ = 1. 🔹 Real-world insights into why sine and cosine are fundamental tools in geometry, physics, and engineering. ⏱ Time Stamps: 00:00 - Intro & Why Sine and Cosine Matter 00:40 - The Unit Circle: Your New Best Friend 03:30 - Cardinal Directions: 0°, 90°, 180°, 270° 06:58 - Friendly Angles: 30°, 45°, 60° 10:49 - Quadrant Symmetry: Signs Change, Ratios Stay! 15:12 - The Never-Ending Cycle: Periodicity of Sine and Cosine 19:05 - The Golden Rule: Pythagorean Identity 📊 More Resources: GitHub - https://github.com/Vitosh/Python_pers...
