A musical cent is a unit in a logarithmic scale of relative pitch or intervals.
One octave is equal to 1200 cents. The formula n = 1200/log2) can be used to
determine the difference in cents between two notes with frequencies a and b.
a. Find the interval in cents when the frequency changes from 443 Hertz (Hz)
to 415 Hz.
b. If the interval is 55 cents and the beginning frequency is 225 Hz, find the
final frequency
