A fun proof of the known geometry fact that the circumference of a circle is pi times its diameter, or 2 * pi * r. I am definitely aware that there are easier methods, like parametrizing the circle or solving the arc length integral in polar coordinates. But the advantage of the method I presented is that it should be easy to follow for someone who hasn’t seen parametric equations before. #math #calculus #integral #geometry #trigonometry #proof
