Amplitude, Period, Phase Shift and Frequency. Some functions (like Sine and Cosine) repeat forever and are called Periodic Functions. The Period goes from one peak to the next (or from any point to the next matching point):. The Amplitude is the height from the center line to the peak (or to the trough). Or we can measure the height from highest to lowest points and divide that by 2.

The following diagram shows how to find the equation of a sine graph. Scroll down the page for examples and solutions. Find an Equation for the Sine or Cosine Wave When finding the equation for a trig function, try to identify if it is a sine or cosine graph. To find the equation of sine waves given the graph 1. Find the amplitude which is half the distance between the maximum and minimum. 2.

Music W rite a sine equation that represents the initial behavior of the.Determine the amplitude, midline, period and an equation involving the sine function for the graph shown in the figure below. Solution To write the sine function that fits the graph, we must find the values of A, B, C and D for the standard sine function D n. The value of D comes from the vertical shift or midline of the graph. The midline is a horizontal line that runs through the graph.

Determining the Amplitude and Period of a Sinusoidal Function. Any motion that repeats itself in a fixed time period is considered periodic motion and can be modeled by a sinusoidal function. The amplitude of a sinusoidal function is the distance from the midline to the maximum value, or from the midline to the minimum value. The midline is the.
