The Language of Waves
Every sound wave, every radio signal, every heartbeat on an ECG monitor follows a mathematical wave pattern. The sine and cosine graphs are the mathematical description of these waves — smooth, repeating curves that oscillate between a maximum and minimum value. Understanding their shape, key points, and transformations allows you to model anything that repeats periodically: tides, seasons, alternating current, and circular motion.
