Webb12 juli 2024 · Our choice of a sine function here was arbitrary – it would have worked just was well to use a cosine. The musical tone, with a frequency of 110 cycles per second, would have a period of \(\dfrac{1}{110}\) of a second. With an amplitude of 3, this would correspond to a function of the form \(3\sin (220\pi {\kern 1pt} t)\). WebbFollowing are the first two plots, the basic cosine function and the function plus errors with variance 1. In the basic plot, the period = 50 and the frequency is 1/50. Thus it takes 50 time periods to cycle through the cosine function. Before errors are added, the maximum and minimum values are +2 and -2, respectively.
