Sine Wave Analysis: Frequency, Period, and Effects of Period Reduction

This assignment provides a detailed analysis of sine waves, focusing on the relationship between frequency and period. It begins by defining a sine wave and its general equation, highlighting the roles of amplitude, frequency, phase shift, and vertical shift. The assignment then focuses on calculating th...Read More

Sine Wave
In trigonometry, a sinusoid or a sine wave is the graph of the sine function.
Generally, the sine wave is represented by the curve whose equation is given by, (Bird, 2017):
y= A sin ( B ( x−C ) ) + D
Where A is the amplitude of the sine function
B is the frequency of the sine wave, that is, the number of cycle from 0 to 2 π.
C is the phase shift of the sine wave, that is, the horizontal shift from the origin.
D is the displacement or the vertical shift of the sine wave.
The simplest form of a sine wave is
y= A sin (Bx ¿)¿
Period, T
The period of the sine wave is given by T = 2 π
