💡 why sin(2x) = 2sin(x)cos(x) by math expansion | GRAPHICAL PROOF 🤯🍎📈 #mathematics
️ In this short video, we explore a beautiful identity in trigonometry: 🤯 sin(2x) = 2sin(x)cos(x) But instead of proving it using traditional algebraic formulas, this video explains it through a graphical and visual method, which makes the concept much easier and more intuitive to understand. First, we observe the graph of sin(x) and cos(x ...
