How to Calculate Sinusoidal Waveforms
Therefore, the sinusoidal waveforms' angular velocity is expressed by the formula. ω = 2πf = rad/sec. In countries wheer the mains AC frequency is 50 Hz, the above equation can be solved as: ω = 2πf = 2π x 50 = 314.2 radians / second. In countries where the mains AC frequency is 60 hz, the above equation becomes:

The equation of a wave (video) | Khan Academy
So, instead of y (x,t) we use x (x,t). But that equation is very confusing since you can't know which is the input x and which is the output. So, it's convenient to replace one of them by a different variable. So, the general equation of a longitudinal wave is:-s (x,t)=Asin (kx-wx) Comment. (1 vote) Upvote.
Sinusoidal Waveform
The RMS velocity of the wave form is given as. Vrms = 0.707 x max amplitude or peak value. = 0.0707 x 150 = 106.05 volts. The angle of a sine wave is a function of its frequency, as we know the sine wave's angular velocity, so we can find out the frequency of the waveform. By using the relation between ω and f.

1.2: Wave Properties
Distributing the factor of 2π λ, and using Equation 1.2.3, we get the final form of the wave function of a 1-dimensional harmonic wave: f(x, t) = Acos(2π λ x ± 2π T t + ϕ) It is common to write this wave function in more compact ways. The first involves the definition of the wave number k, and angular frequency ω:

Average Voltage of a Sinusoidal AC Waveform
VAV = Vpk x 0.637 = 20 x 0.637 = 12.74 volts. Which is the same value as for the graphical method. To find the peak value from a given average voltage value, just rearrange the formula and divide by the constant. For example, what is the sinusoidal peak value, V pk if the average value is 65 volts. Vpk = VAV ÷ 0.637 = 65 ÷ 0.637 = 102 volts.

Understanding Sinusoidal Wave Signals | Electrical4U
Summary. A sinusoidal wave signal is a type of continuous wave that has a smooth and repetitive oscillation. It is based on the sine or cosine trigonometric function, which describes the curve of the wave.
