Sounds are how we perceive pressure waves in the air. The note F-sharp, more than 2 octaves below the note 'middle C', is a sound wave with an ordinary frequency* f - 61.875 Hertz or cycles/sec Model this note with the sine function, assuming that the amplitude is 1 and the phase shift is 0. g(x) The temperature during the day can be modeled by a sinusoid. Answer the following question given that the low temperature of 30 degrees occurs at 3 AM and the high temperature for the day is 70 degrees. Assuming t is the number of hours since midnight, find an equation for the temperature, T, in terms of t. T(t)
