The angle.
Basically, it IS a curve.
Cosine
The sine curve is exactly the same as the cosine curve shifted pi/2 radians to the left
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.

The sine wave is also called a sinusoid is a mathematical curve that describes the smooth repetitive oscillation.
The curve is shifted to the right by c.
One way is to shift it to the left by a quarter of the period.
You can move a sine curve up or down by simply adding or subtracting a number from the equation of the curve. For example, the graph of y = sin x + 4 moves the whole curve up 4 units, with the sine curve crossing back and forth over the line y = 4. On the other hand, the graph of y = sin x - 1 slides

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.
