Common Mistakes When Using “fourier”

- Pronouncing it as /faʊˈriːər/ (like 'four' + 'ear').
FAQ
Frequently Asked Questions
Yes. It is a proper noun (a surname) and must be capitalised, even when used attributively (e.g., Fourier series).
Not in standard English. In highly informal technical jargon, it is sometimes used as a verb meaning 'to apply a Fourier transform to' (e.g., 'Fourier the data'), but this is non-standard.
It is the concept that any complex, periodic wave can be represented as a sum of simple sine and cosine waves of different frequencies, amplitudes, and phases.
Yes. A Fourier series represents a periodic function as a sum of sinusoids. A Fourier transform is a more general operation that decomposes a non-periodic or localized function into its frequency components across a continuous spectrum.
A proper noun primarily referring to the French mathematician and physicist Jean-Baptiste Joseph Fourier (1768–1830).
Fourier is usually academic/technical/formal in register.
Fourier: in British English it is pronounced /ˈfʊə.ri.eɪ/, and in American English it is pronounced /ˈfʊr.i.eɪ/ or /ˈfɔːr.i.eɪ/. Tap the audio buttons above to hear it.
