A sine wave is, theoretically at least, the naturally-generated voltage produced by any rotating machine. This is because the voltage induced into a conductor that rotates within a magnetic field is proportional to the sine of the angle at which the conductor cuts the magnetic flux. In practise, a perfect sine wave is not produced in most practical machines, but it is close enough for practical purposes.

When a low pass filter is used with a sine wave input, the output is also a sine wave. The output will be reduced in amplitude and phase shifted when the frequency is high, but it is still a sine wave. This is not the case for square or triangular wave inputs. For non-sinusoidal inputs the circuit is called an integrator.
cos wave
A sine wave has no harmonics. It only has a fundamental, so the value of the 2nd, 3rd, and 12th harmonics of a sine wave is zero.
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 isn't as such, it is a consequence of generating electricity using a rotary method - the voltage generated is proportional to the sin of the angle between the magnetic field and the coil, and the angle changes due to rotation.
In most circumstances a full wave diode bridge is used to convert AC into DC. Along with inductors and capacitors used as filters, the DC ripple is smoothed out to a very stable DC voltage. This is the method used in DC power supplies. To convert from DC to AC an inverter is used. Today most inverters use the modified sine wave method which brings the sine wave closer to a AC generated sine wave. Older inverters used an on - off switching procedure to generate a square sine wave. Modern electronics do not work well with square wave generation.
The sine wave is a mathematical function that describes a smooth repetitive oscillation. An Inverter is an electronic device that converts power from one voltage to another.A pure sine wave inverter is a device that produces a smooth and consistent flow of electricity in the required voltage.The benefits of a pure sine wave inverter are that the device requiring the electricity from the inverter will not suffer from surges and lows in power output and as such the connected device will perform a lot better.

When a low pass filter is used with a sine wave input, the output is also a sine wave. The output will be reduced in amplitude and phase shifted when the frequency is high, but it is still a sine wave. This is not the case for square or triangular wave inputs. For non-sinusoidal inputs the circuit is called an integrator.
If a square wave is used instead of a sine wave in a transformer, the output power will operate at a different frequency. This will produces varying levels of voltage and amperage based on the wave.
A sine wave is the graph of y = sin(x). It demonstrates to cyclic nature of the sine function.
