The sine wave or sinusoid is a function that occurs often in mathematics, physics, signal processing, electrical engineering, and many other fields. Its most basic form is:
Square wave Trigonometric functions Fourier analysis Signal processing Fourier transform Direct current Non-sinusoidal waveform Sinusoidal model Pure tone Instantaneous phase Frequency Helmholtz equation Triangle wave Harmonic series (mathematics) Sawtooth wave Tuning fork Phase velocity Simple harmonic motion Wavenumber Harmonic series (music) Whistling Periodicity Joseph Fourier Angular frequency Wave equation Rectifier Speech Ocean surface wave Dot product Radian Harmonic Fourier series Hearing (sense) Phase (waves) Absolute value Timbre Wave Amplitude Alternating current Ear
