@glythify: 🧮 Cosine Function Deep Dive | Unit Circle + Graph Combo #CosineFunction #TrigTutorial #UnitCircle #PrecalculusHelp #HighSchoolTrig #MathVisuals #GraphingTrig 🔁 Ever wondered why cos(x) = 1 at x = 0? Let’s visualize it! In this video, we dive into the cosine function through the lens of the unit circle and graph, using the point where cos(x) = 1 as our starting anchor. 📘 What you’ll learn: How cosine is defined on the unit circle Why cos(x) = 1 at x = 0 How that value translates to the cosine graph Visual patterns in trig functions 💬 Comment below with YOUR most confusing trig concept — I’ll break it down in the next video!
