Because the laws of basic AC circuit theory only apply to a true sine wave. Other waveforms, such as square or sawtooth, are imperfect recreations of a sine wave with many harmonic frequencies present.

What are the advantages of the sine wave compare to other form of waves?

None - except that we have a grasp of the mathematical properties of sine waves. Sine waves seldom occur in nature ... but they often come close enough to be approximated by a sine wave.


Sine wave can be split into?

a)set of sine waves b)set of sine waves with phase zero


Why the cos wave is smoother from sine wave?

Neither wave is smoother than the other. However, the two waves are usually evaluated from 0 to 2*pi, and in that case, the cosine wave begins at y=1, and the sine wave begins at 0.


What is the difference between pure sine wave and modified sine waves?

A pure sine wave has energy at only one frequency.Any other wave shape has energy at other frequencies in addition to the frequency of the obvious waveshape.If you add up enough sine waves with the right frtequencoies and amplitudes, they'll add up to form any shapeyou want, even a squarewave.


What do sound waves have to do with trigonometry?

Sound waves and other types of waves have sinusoidal graphs. The graph of a sound with a single frequency is a sine wave. More complicated sounds contain multiple frequencies, and their graphs can be obtained by summing up sine waves. Other sorts of waves, not just sound waves, can also be analysed as sums of sine waves. This includes light and changing electrical currents.


What is a complex waveform?

It is a sine wave form coupled with either a DC component or other sine waves or both.The official definition of the word waveform is "a curve showing the shape of a wave at a given time."


How is trig used in life?

The obvious answer is the relationships between the sides and angles of triangles. Waves in the sea are an example of a sine wave. Tidal Experts and Meterologists alike use sine waves to help predict tides. Music will also emit waves that may often look like a sine wave and pure notes will look like sine or cosine waves. The speed of a swinging pendulum can be plotted as a sine wave as well as the sound of a tuning fork.


How sine wave generate?

Do you mean "How do sine waves generate ?" Or perhaps you mean "How are sine waves generated?" Or something else, perhaps? No one can answer a question that is incomprehensible.


Can transverse waves resemble a sinusoidal wave?

If you graph the displacement (or some other physical change) over time, you'll quite often get a sine wave.


If Sine wave A and sine wave B are each ten kHz but B is delayed by 8.5 micro seconds from A The phase difference between the waves is?

What is sine waves?

See the link belowA sine wave is computed by a mathematical function. A pure sine wave in a physical sense would exactly match the calculated value in the function at every point in time.


The easiest type of wave to visualize is a?

sine wave. It is a smooth, repetitive oscillation that is easy to represent graphically as a simple curve. Sine waves have a clear pattern that is easy to predict and visualize.
