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)
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).
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."
On a sine wave, the voltage is equal to zero at every integer multiple of 180 degrees. This occurs at 0 degrees, 180 degrees, 360 degrees, and so on. These points represent the crossings of the waveform along the horizontal axis, where the sine function equals zero.
To measure an AC sine wave using an oscilloscope, first connect the probe to the circuit where the AC signal is present. Set the oscilloscope to an appropriate voltage scale and time base for the expected frequency of the sine wave. Adjust the vertical and horizontal controls to clearly display the waveform on the screen. Once displayed, you can analyze the waveform by measuring parameters such as peak-to-peak voltage, frequency, and period directly from the oscilloscope's readout or by using the cursor function for more precise measurements.
If you put a diode in series with an AC sine wave that goes plus and minus, it will cut off either the positive or negative portion of the waveform, depending on the direction of the diode in circuit. So in effect you have a pulse equal to one half cycle of the sine wave.

Should be a sine ( or cosine) wave.

A: ANALOGUE IT can be AC or DC it is up to the application involved An analog signal can be a sine wave, a square wave a sawtooth wave or any other varying waveform
Sine wave
The wave in amplitude modulation must be a sine wave. A sine wave represents smooth repetitive oscillation, which is necessary for this process.
The period of 1GHz is 1 ns. The waveform is irrelevant.
Look up sine wave on Google to see a picture.
The period of 1 MHz is 1 microsecond. The waveform is irrelevant.
It can take (almost) any form, but what comes out of your wall is close to a sine-wave.
No load current is mostly inductive, hence the load current may not be a 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.
