these are angular velocity & time. Sine(wt)
By shifting the sine wave by 45 degrees.
Neither wave is smoother than the other. However, the two waves are usually evaluated from 0 to 2*pi, and in that case, the cosine wave begins at y=1, and the sine wave begins at 0.
A sine wave is the graph of y = sin(x). It demonstrates to cyclic nature of the sine function.
The voice is not a sine wave.
A wave is composed of an amplitude and a wavelength. A transverse wave contains oscillations perpendicular to the direction the wave is traveling, for instance, a sine wave.
a phase shifted sine wave of a different amplitude.
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).
The sine wave, with its repeating pattern, can represent a single frequency with no harmonics.
The differential of the sine function is the cosine function while the differential of the cosine function is the negative of the sine function.
it's a sine wave
