sine 40° = 0.642788
The sine of 75 degrees is about 0.9659
Sine Pari is Latin for "without equal".
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.
frequency of 10 hertz
A cycle is one complete revolution of the sine wave. Hertz is the frequency of the alternating current, how many complete cycles per second. 60 Hertz would have 60 cycles each second.
The phase angle varies from 0 to 360 degrees as the wave cycles.
5 cycles.
The voltage and current are delivered in a sine wave that goes positive and then negative at 60 cycles per second. Google sine wave to see what a sine wave looks like.
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.
An AC waveform is a sine wave and varies from positive to negative with a frequency of 60 Hertz (Cycles per Second). DC is a constant voltage and does not vary like the sine wave.
For a standard 360 deg sine wave with starting point of 0 deg, peaks will occur at 90 deg and 270 deg.
One cycle of a 125hz sine wave would last .008 seconds. Hz (hertz) refers to the frequency of the wave itself, that is, how many times the wave cycles in a second. To find the cycle length, then, simply divide 1 second by the frequency, in this case: 1/125 = .008.
If "your wall" is in North America then the answer is 60 Hertz (Hz) or 60 cycles per second in the form of a sine wave.
The average value of a sine wave is 0. That's by integrating the function over a whole (or any integer number of whole-) cycles and dividing by the total time, n*T. In a "pure" sine wave, i.e., one with zero distortion, one half cycle has some total integral that's a sum of positive values, while the second half cycle is all *below the axis*, so negative in value and symmetrical with the first half. So when you add the two (or n*2) half cycles--which is integration--you get a sum of zero. No matter the frequency, or amplitude of the sine wave.
This question makes no sense as the specified condition cannot occur. The phase shift between a sine wave and a cosine wave is always 90 degrees, by definition.
