Title: A visual proof of the double-angle formula for sine
Type of Resource: Animação/simulação
Abstract: The double-angle formula for sine states that sin(2x) = 2sin(x)cos(x). Computing the area of a triangle using the formula A = (b*h)/2 (area equals one-half base times height) gives sin(2x) for the top triangle and 2sin(x)cos(x) for the bottom triangle
