sine wave
Sine wave is considered as the AC signal because it starts at 0 amplitude and it captures the alternating nature of the signal. Cosine wave is just a phase shift of the sine wave and represents the same signal. So, either sine or cosine wave can be used to represent AC signals. However, sine wave is more conventionally used.

When a low pass filter is used with a sine wave input, the output is also a sine wave. The output will be reduced in amplitude and phase shifted when the frequency is high, but it is still a sine wave. This is not the case for square or triangular wave inputs. For non-sinusoidal inputs the circuit is called an integrator.
The Fourier transform of a sine wave is a pair of delta functions located at the positive and negative frequencies of the sine wave.
If a square wave is used instead of a sine wave in a transformer, the output power will operate at a different frequency. This will produces varying levels of voltage and amperage based on the wave.
A sine wave is the graph of y = sin(x). It demonstrates to cyclic nature of the sine function.
The voice is not a sine wave.
The sine wave formula is y A sin(Bx C), where A represents the amplitude, B represents the frequency, and C represents the phase shift. To calculate the amplitude, you can find the maximum value of the sine wave. To calculate the frequency, you can determine the number of cycles that occur in a given time period.
Lissajous figures are observed when two simple harmonic motions are perpendicular to each other. These figures can be generated by plotting the motion of a point on a plane as it moves according to the two harmonic motions. They are commonly seen in the study of oscillations and wave phenomena.
