i dont know,,,give me ans
Form factor is (RMS value)/(average absolute value) For sine wave form factor = (1/sqrt(2))/(2/pi) = about 1.11
form factor tell about the purity of sine wave
It's hard to define a sound, but here's a try: A half-wave rectified sine sounds harsh and whiney. Not as sharp and jagged as a square wave, but not nearly as pure and smooth as a sine. The key is to realize that the half-wave rectified sine is a sine plus a significant load of harmonics, and wherever there is a lot of harmonic energy, we call it "total harmonic distortion". So the bottom line is, anything that isn't a pure sine, you would say it sounds "distorted".
due to the form factor .as the form factor of sine wave is 1.1 so, we use its multiples .
Draw a sine wave, except that when it wants to go negative, keep it at zero instead.
Form factor of any periodic wave is [RMS CURRENT]/[AVERAGE CURRENT]. For sinusoidal wave RMS current=I/sqrt(2); AVERAGE current=2I/pi; Therefore, Form factor=[I/sqrt(2)]/[2I/pi] =pi/{2*sqrt(2)} =1.11

To find which angle has a sine of 0.13, you calculate arcsin or sin^-1(0.13) =7.47 degrees 7.47 degrees has a sine of 0.13. There is also another angle , below 360 , has a sine of 0.13. Subtract 7.47 from 180. 180-7.47 = 172.53 degrees also has a sine of 0.13.
Using its Taylor-series.
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.
y = sin(x)
You can calculate that on any scientific calculator. Just make sure that the calculator is set to "degrees". As a check, the sine of 90° should come out as exactly 1.
