   In other words, the inverse of B (1/B) is equal to the base wave talking in period terms. For example, in the graph of y = sin 2 x shown above, the period is two times as short as the period of the base graph of y = sin x.

   The logarithmic curve isn't likely to fit the data because it has a "L" like shape meaning that the initial years would be very far away from the model. The model I will develop will depend on how well it seems to fit into the data point set.

   To visualize these frequency patterns, we will graph a single note, in this case, we will use A4, the most commonly used note for a general tuning standard for musical pitch, which has a frequency of 440 Hz. The equation for A4 is: The graphing of a sine function allows us to visualize the oscillation of the string.
