Sinusoidal: meaning, definitions and examples
➿
sinusoidal
[ ˌsɪnəˈsɔɪdəl ]
mathematics, waveforms
Sinusoidal describes a shape or pattern that resembles the sine wave, typically involving smooth, periodic oscillations. This term is often used in mathematics and physics to describe functions or signals that oscillate in a regular and predictable manner.
Synonyms
oscillatory, sine-shaped, wave-like
Examples of usage
- The signal had a sinusoidal pattern.
- They analyzed the sinusoidal waveforms in the experiment.
- Sinusoidal functions are foundational in trigonometry.
Word origin
The word 'sinusoidal' has its origins in the Latin term 'sinus,' meaning 'bay' or 'curve,' which in mathematical contexts refers to the curve created by the sine function. The term was popularized with the development of trigonometry in the early 17th century, when mathematicians explored the properties of the sine function. Its use has expanded into fields like engineering, physics, and signal processing, where sinusoidal waves play a crucial role in understanding oscillatory systems and waveforms. The concept continues to be pivotal in both theoretical and applied sciences, particularly in analyzing periodic phenomena.
