🧠 Unlock the Law of Cosines with This Simple Proof! #LawOfCosines #trigonometry #GeometryHelp #TriangleIdentities #MathProofs #HighSchoolMath Ever wondered where the Law of Cosines actually comes from? Let’s prove it step by step. ✏️ In this video, we derive the Law of Cosines from scratch using triangle geometry and coordinate-style reasoning. This proof is crucial for understanding how trigonometry extends the Pythagorean Theorem for non-right triangles. We start with a triangle labeled with sides a, b, and c, and use geometric constructions: Drop a perpendicular to create a right triangle Use the Pythagorean Theorem Express side lengths using cosine This leads us to the final, powerful result: c^2 = a^2 + b^2 - 2ab\cos(C) 📘 You’ll Learn: How to break triangles into right triangles to prove identities The logic behind projecting side lengths using \cos(C) A clear connection between algebra and trigonometry Why this identity generalizes the Pythagorean Theorem 🎯 Why this matters: This proof is foundational in high school trigonometry, Precalculus, and Math Olympiad prep. Knowing why a formula works helps you remember and apply it more effectively. 💬 Comment below with YOUR most confusing trig identity, and I might prove it in the next video!
