Use the two-harmonic equation for the annual cycle from Exercise 9.6 to estimate the mean daily temperatures for

a. April 10.

b. October 27.

Exercise 9.6

For the temperature data in Table 9.7,

a. Calculate the first two harmonics.

b. Plot each of the two harmonics separately.

c. Plot the function representing the annual cycle defined by the first two harmonics. Also include the original data points in this plot and visually compare the goodness of fit.
