The general form of a sinusoidal wave is



Y = A Sin (ωt + φ)

A is the amplitude of the wave, that is the maximum value of the sinusoid wave


Angular frequency ω = 2πf

Where f is the frequency of the wave.


φ is the phase angle of the wave


(In electrical engineering the phase angle is usually expressed in degree)

Time period     T  =   1 f
