Title: 4_5 Applications of Trigonometry to Waves
Course: HELM Workbooks 2023-2024 > Section: HELM 4: Trigonometry

Waves and vibrations occur in many contexts. The water waves on the sea and the vibrations of a stringed musical instrument are just two everyday examples. If the vibrations are simple ‘to and fro‘ oscillations they are referred to as ‘sinusoidal‘   which implies that a knowledge of trigonometry, particularly of the sine and cosine functions, is a necessary pre-requisite for dealing with their analysis. In this quiz we give a brief introduction to this topic.
