Cosine
The sine curve is exactly the same as the cosine curve shifted pi/2 radians to the left
The angle.
Sound waves are transmitted through a medium as variations in the pressure of the medium. If the variation is plotted as a function of distance (or time), they will generate a sine curve (the cosine curve is the same as a sine curve with a phase shift). In practise, the sine curve is damped: the amplitude (or height) of the oscillations gradually decrease over time or distance, because of attenuation.
One way is to shift it to the left by a quarter of the period.

In physics, a sine curve is used to represent periodic phenomena such as simple harmonic motion or alternating current. It shows how a quantity varies sinusoidally with time or distance. The amplitude, frequency, and phase of the sine curve provide important information about the behavior of the system being studied.

The sine wave is also called a sinusoid is a mathematical curve that describes the smooth repetitive oscillation.
One way is to shift it to the left by a quarter of the period.
The curve is shifted to the right by c.
a normal sine curve exists with the formula Asin(Bx+C)+D. The formula to derive a phase shift would be such: 2pi/B (for whatever value B exists at). Thus, for a normal sine curve (sin(x) we would get 2pi/1, and arrive at 2pi for the period.
Sine curve
The amplitude of a sine (or cosine) curve is the difference between the maximum and minimum values of the curve, measured over a whole cycle.
Cosine (0) = 1 Sin(0) = 0 The sine and cosine curves are two intertwining curves, that complement each other, hence the words 'Sine (Curve) and Cosine ( COmplementary Curve).
