sine wave equation explained A sine wave sinusoidal wave or sinusoid symbol is a periodic wave whose waveform shape is the trigonometric sine function In mechanics as a linear motion over time this is simple harmonic motion as rotation it corresponds to uniform circular motion
The equation below is the generalized form of the sine function and can be used to model sinusoidal functions This equation may also be colloquially referred to as the sinusoidal function formula or sinusoidal function equation Sinusoidal function formula y A sin B x C D where A B C and D are constants such that is the period A particularly simple kind of wave the sine wave is illustrated in figure 1 2 This has the mathematical form h x h 0 sin 2 pi x lambda label 1 1 where h is the displacement which can be either longitudinal or transverse h 0 is the maximum displacement also called the amplitude of the wave and is the wavelength The

To write a sine function you simply need to use the following equation f x asin bx c d where a is the amplitude b is the period you can find the period by dividing the absolute value b by 2pi in your case I believe the frequency and period are the same c is the phase shift or the shift along the x axis and d is the vertical The graph of y sin x is like a wave that forever oscillates between 1 and 1 in a shape that repeats itself every 2 units Specifically this means that the domain of sin x is all real numbers and the range is 1 1 See how we find the graph of y sin x using the unit circle definition of sin x
Definition A sine wave or sinusoid is a mathematical curve that describes a smooth periodic oscillation A sine wave is a continuous wave It is named after the trigonometric function sine of which it is the graph It occurs often in both pure and applied mathematics as well as physics engineering signal processing and many other fields For y sin 2X the total steps required to finish one cycle is shown as below total steps total distance distance per steps total steps 2pi 2 total steps pi So if he walk TWO steps at a time the total number of step to finish one
