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."
It's called a sine wave because the waveform can be reproduced as a graph of the sine or cosine functions sin(x) or cos (x).
Since a sine wave is described by the trigonometric sin(x) function, which is symmetrical, the sine wave is also symmetrical, unless there is a DC bias, in which case it is not. (It depends on your definition of symmetry)
Out of phase means that the sinusoidal waveform of voltage and/or current is not exactly in step with the reference phase. Expressed mathematically, it means that the coefficient of the sine function for one parameter is not the same as the other parameter. One may be x, and the other may be x+120. (This is an example of two phases in a three phase power system.) Another example might be where voltage is x, and current is x-23. This would be a case of a power factor of 0.92, such as for a typical large induction motor with a reactive phase angle of 23 degrees.
Advantage 1. Different waveform upto mhz freq. Can be generated 2. it can be used to generate square, sine, triangular and sawtooth waveforms 3. calibration is internal. Disadvantage They are usually not suitable for applications that need low distortion or stable frequency signals.
Power Factor is the relationship between the phase of the current and voltage which are each sine waves. When there is an inductance in a circuit the AC current waveform tends to lag the voltage. This causes a phase difference which reduces the Power Factor from a maximum of one to something less.
The frequency of the power waveform in a capacitive circuit, or for that matter, an inductive circuit, is the same as the input voltage or current. Its just that the current leads the voltage (capacitor) or lags the voltage (inductor) by a phase angle, the cosine of which is the power factor. It does not matter how many sine waves you have, or what their phase angle is; if they all have the same frequency, the resultant, by Fourier analysis, is still a sine wave of the same frequency.
Should be a sine ( or cosine) wave.

Sine wave
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.
The period of 1GHz is 1 ns. The waveform is irrelevant.

Look up sine wave on Google to see a picture.
a)set of sine waves b)set of sine waves with phase zero
