## Find a Sinusoidal Function Given its Graph.

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.

Amplitude and Period for Sine and Cosine Functions Worksheet Determine the amplitude and period of each function. y: sin 4x y: 4 cos x y: 3 sin —x cos 5x 2 sin x 4 cos 5x Give the amplitude and period of each function graphed below. Then write an equation of each graph. 12. —2 It 13. —2 It f'. ZIT Give the amplitude and period of each.

In this video David shows how to determine the equation of a wave, how that equation works, and what the equation represents. If you're seeing this message, it means we're having trouble loading external resources on our website.

Write the equations for two limacons (and if possible graph), (one sine and one cosine) with the same a and b values. (A does not have to equal b). You may choose to use cardioids or inner loop, dimpled, or convex limacons.

You can write the equation of a trigonometric function if you are given its graph. Write an equation for each graph. Because the graphk y-intercept is 0, the graph is a sine function. Since the maximum and minimum values are 2 and —2, respectively, the graph is a vertical stretch of the parent sine function by a factor of 2. So, a — 2.
