If you're referring to a triangle waveform, it's commonly used for bass in NES music.
y!
The period of 1GHz is 1 ns. The waveform is irrelevant.
Since a sinusoidal waveform is really based off of a rotating circle you can describe its position in time using polar coordinates (magnitude, phase angle) OR put that circle on a Cartesian plane and describe it with normal x and y coordinates (instead of x and y we call it real and imaginary because the sinusoids we see are really just the up and down parts, aka 1 of the 2 dimensions, of the entire rotating circle).
The period of 1 MHz is 1 microsecond. The waveform is irrelevant.
Amplitude, frequency/period and phase.
Complex waveforms can be produced by combining multiple sinusoidal waves of different frequencies, amplitudes, and phases. This process is known as waveform synthesis. By varying the characteristics of the sinusoidal waves and their relationships to each other, a wide variety of complex waveforms can be generated, such as square waves, sawtooth waves, and triangle waves.
As a sinusoidal signal is clipped the waveform approaches a square wave.
Either sinusoidal, or can always be represented as a sum of sinusoids.
No load current is mostly inductive, hence the load current may not be a sine wave
The main advantage of using sinusoidal waveform is that any waveform can be represented using a sinusoidal wave (by applying Fourier series). Also, analysing a circuit (or any other system) becomes simpler and easier using sinusoidal signal as test signal.

Because this is the shape of the waveform naturally generated by a conductor that is cut by a rotating magnetic field. It would be extremely difficult, as well as unnecessary, to generate any other shaped waveforms. You should also understand that square and triangular waveforms are normally made up of sinusoidal waveforms of different amplitudes and frequencies (check out 'Fourier analysis').
AC generators have a varying waveform which is sinusoidal in nature, whereas a DC output is linear.
How loud the air vibration is from the bell of the instrument. Technically the maximum zero to peak value (0-90 degrees) of the sinusoidal waveform.
General formula: square root of the square modulus averaged over a period:xRMS =1/T sqrt( integral (|x(t)|2dt) ) ,where x(t) is the signal and T is its period.If you solve it for sinusoidal waves, you get a 1/sqrt(2)~0.707 factor between peak amplitude and RMS value:xRMS ~ 0.707 XPK ~ 0.354 XPK-PK ~ ...
