WebMar 26, 2016 · The amplitude of the sine function is the distance from the middle value or line running through the graph up to the highest point. In other words, the amplitude is half the distance from the lowest value to the highest value. In the sine and cosine equations, the amplitude is the coefficient (multiplier) of the sine or cosine. WebAmplitude = _____ Period = _____ 21. Find an equation for a sine function that has amplitude of 4, a period of π. 22.

7.4: Modeling Changing Amplitude and Midline
WebMay 4, 2024 · Given a graph of a sine or cosine function, you also can determine the amplitude and period of the function. From this information, you can find values of \(a\) and \(b\), and then a function that matches the graph. Remember that along with finding the amplitude and period, it’s a good idea to look at what is happening at \(x = 0\). WebThe 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.
