# Sine wave

An ideal

**sine wave** is a

waveform that is identical to (the

graphss of each wave are the same as) the generalized

sine function

*y* =

*A*sin[

*ω*(

*x* −

*α*)] +

*C*, where

*A* is the

amplitude,

*ω* is the

angular frequency (2π/

*P* where

*P* is the

wavelength),

*α* is the

phase shift, and

*C* is the vertical offset.
