Find a real-world situation that can be represented by a sinusoidal function. you may find something online that represents a sinusoidal graph or you can create a sinusoidal graph yourself with a measuring tape and a rope. provide a graph complete with labels and units for the x- and y-axes. describe the amplitude, period, and vertical shift in terms of the real-world situation. read and reply to at least two other students posts and answer the following questions: describe how the real-world situation would have to change if you wanted to change the period. what would have to change in the real-world scenario to stretch the amplitude?
