In the video, a person is seen holding a piece of paper with mathematical equations written on it. The person is using their finger to point at the equations, presumably explaining the concepts behind them. The equations appear to be related to trigonometry, as they include the sine and cosine functions. The person's hand movements suggest that they are explaining the equations in a step-by-step manner, possibly for educational purposes. The background is not visible, focusing the viewer's attention solely on the paper and the person's hand movements.
