Why you are considering sine wave as ac but not cosine 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.
What is mean by sweep rate in vibration?
"sweep rate" refers to "how fast" you go through a frequency range when performing a vibration test. For example, let's put an equipment on a shaker and see how it responds to a sine excitation having a frequency between 50 and 2000Hz. The rate at which you will vary the frequency between 50 and 2000Hz is called the "sweep rate". It can be measured in Hz/min or octave/min.
What is the Fourier transform of a sine wave?
The Fourier transform of a sine wave is a pair of delta functions located at the positive and negative frequencies of the sine wave.
What does the sine wave represent physically?
In the physical realm, a sine wave represents a smooth periodic oscillation or vibration that can describe various natural phenomena such as sound waves, alternating current electricity, and simple harmonic motion like a swinging pendulum. It is characterized by its properties of amplitude, frequency, and phase.
When was Surfing on Sine Waves created?
Surfing on Sine Waves was created on 1993-01-11.
How is trigonometry used in music?
For any pure note, the vibration of the string or the compression waves of air is a sine (or cosine) curve. Harmonic notes are sine curves whose frequencies are multiples of the basic frequency.
What is the motion called when you are playing a bell?
The sound coming from the bell, and the vibration of the bell itself, is described as simple harmonic motion. The graph would be a diminishing sine wave.
What is the sine of 810?
sine 810 = sine 90 = 1
What is the importance of trigonometry in the field of sound?
The compression and rarefaction of the medium in which the sound is propagated can be modelled by a sine curve. You can see a half-wave in the vibration of a string on musical instruments or even a stretched elastic band.
If two integers have the same sign what is the sine of their sum?
Sine(A+ B) = Sine(A)*Cosine(B) + Cosine(A)*Sine(B).
What is the value of sine 3.3?
Sine 3.3 degrees is about 0.057564. Sine 3.3 radians is about -0.157746. Sine 3.3 grads is about 0.051813.
Why domain of sine is -infinity x infinity?
Because the argument of the sine function can have any real value. In fact, it can extend beyond that but that is for more advanced level students.

What has the author M W Kehoe written?
M. W. Kehoe has written: 'Modified U.S. Army U-8F ground vibration test' -- subject(s): Modal analysis, Testing, Airplanes 'Correlation of analytical and experimental hot structure vibration results' -- subject(s): Airplanes, Design and construction 'Ground vibration test results of a JetStar airplane using impulsive sine excitation' -- subject(s): Testing, Airplanes
What is sine infinity?
Sine does not converge but oscillates. As a result sine does not tend to a limit as its argument tends to infinity. So sine(infinity) is not defined.
Which is more reasonable using a sine wave or square wave signal to determine slew rate?
It is more reasonable to use square wave rather than sine wave signal to determine slew rate. Both signal sources serve as a functional generator with the sine wave providing high purity waves.Ê
What is the meaning of sine dine?
