PLEASE HELP!! The science of physics, specifically waves and harmonics, goes hand in hand with the mathematics of trigonometry. We need trigonometry to model the path of a wave traveling through the air or water. Describe another connection between a math topic and a non-math topic,
where the math topic is needed to explain and model the non-math topic.
