Ever wondered why you had to learn trigonometry in school? In this video, we break down sine, cosine, and tangent in the most intuitive way possible... using real-world examples like spacecraft orbiting Earth. Instead of memorising formulas like SOHCAHTOA, you’ll finally understand where these concepts come from and how they actually work. We explore right-angle triangles, the unit circle, and how trigonometric functions create the sine and cosine graphs you see in maths. Whether you’re revising for GCSEs, A Levels, or just curious about how maths applies in real life, this video will completely change the way you see trigonometry. -------- ❤️ Support my channel ❤️ 👤 Become a Member:    / @elliesleightholm   💸 Patreon:   / elliesleightholm   ☕️ Buy Me a Coffee: https://buymeacoffee.com/elliesleight...
