Example 5: Finding the Frequency of a Musical Note Consider the tuning fork data in Table 1.18 (Finney, page 49). (a)Find a sinusoidal regression equation (general sine curve) for the data and superimpose its graph on a scatter plot of the data (b)The frequency of a musical note, or wave, is measured in cycles per second, or hertz (1 Hz = 1 cycle per second). The frequency is the reciprocal of the period of the wave, which is measured in seconds per cycle. Estimate the frequency of the note produced by the tuning fork. NOTE: there are many data points, so rather than do this in class, I will simply reprint what is in your textbook

Inverse Trigonometric Functions None of the trigonometric functions is one-to-one We can define inverse trigonometric functions by appropriately restricting their domains Recall that, for the inverse of a function, the domain and range switch roles Hence, in order to appropriately restrict the domains of the trigonometric functions, we must consider their range; an inverse function must cover the entire range (which becomes the domain)
