- Sinusoidal Graphs
The Sinusoidal Function Calculator plots the trigonometric functions sin(x), cos(x), and tan(x) given the period, amplitude, vertical, and phase shift values. The calculator shows two plots: one is over a smaller range of x (zoomed in), and the other is over a larger interval of x (zoomed out).

Equation of a sinusoidal curve. Given the graph of a sinusoidal function, we can write its equation in the form y = A·sin (B (x - C)) + D using the following steps. D: To find D, take the average of a local maximum and minimum of the sinusoid. y=D is the "midline," or the line around which the sinusoid is centered.
Sine wave calculator. Construction of a sine wave with the user's parameters. This calculator builds a parametric sinusoid in the range from 0 to. Why parametric? Because the graph is represented by the following formula. , and the coefficients k and a can be set by the user.

For example, at times t 1 and t 1 + T, the sinusoidal wave takes the same value, y(t 1) = y(t 1 + T) = -A. This holds for any multiple of T, meaning y(t 1 ) = y(t 1 + kT) = -A where k = 1, 2, 3, and so on.
